In the final years of his life, the Belgian phenomenologist Marc Richir started to question if philosophical writing would become pointless when artists, great poets for example, have already achieved so well what philosophers have always aspired to achieve. There is no doubt that Richir considers himself in alliance with artists, since he basically believes that “phenomenology is trying to say the same thing as poets or musicians, or even possibly painters, but with philosophical language”. He seems thereby to imply (...) that phenomenology is destined to become self-aware as a sort of art. There is no surprise in this regard if we notice how frequently, throughout his entire career of philosophical production, he employs the Kantian term of the sublime to express what constitutes the phenomenon as nothing but phenomenon. This article goes through his phenomenological interpretation of Kantian aesthetics, his elaboration of the affinity between phenomenology and art, and then his genealogical conception of art, in order to introduce an original thought on what he calls “the moment of the sublime”.

Sleep researchers in different disciplines disagree about how fully dreaming can be explained in terms of brain physiology. Debate has focused on whether REM sleep dreaming is qualitatively different from nonREM (NREM) sleep and waking. A review of psychophysiological studies shows clear quantitative differences between REM and NREM mentation and between REM and waking mentation. Recent neuroimaging and neurophysiological studies also differentiate REM, NREM, and waking in features with phenomenological implications. Both evidence and theory suggest that there are isomorphisms between (...) the phenomenology and the physiology of dreams. We present a three-dimensional model with specific examples from normally and abnormally changing conscious states. Key Words: consciousness; dreaming; neuroimaging; neuromodulation; NREM; phenomenology; qualia; REM; sleep. (shrink)

Dreams are a remarkable experiment in psychology and neuroscience, conducted every night in every sleeping person. They show that the human brain, disconnected from the environment, can generate an entire world of conscious experiences by itself. Content analysis and developmental studies have promoted understanding of dream phenomenology. In parallel, brain lesion studies, functional imaging and neurophysiology have advanced current knowledge of the neural basis of dreaming. It is now possible to start integrating these two strands of research to address fundamental (...) questions that dreams pose for cognitive neuroscience: how conscious experiences in sleep relate to underlying brain activity; why the dreamer is largely disconnected from the environment; and whether dreaming is more closely related to mental imagery or to perception.

As a topic in the philosophy of psychology, dreaming is a fascinating, diverse, and severely underdeveloped area of study. The topic excites intense public interest in its own right, while also challenging our confidence that we know what the words “conscious” and “consciousness” mean. So dreaming should be at the forefront of our interdisciplinary investigations: theories of mind which fail to address the topic are incomplete. This chapter illustrates the tight links between conceptual and empirical issues by highlighting surprisingly deep (...) disagreements among leading dream scientists over what might seem basic aspects of their topic.

The Dreaming Mind provides an insightful, interdisciplinary approach to the study of dreaming, exploring its nature and examining some of the implications of dream states for theories of consciousness, cognition and the self. Offering an integrative approach into our understanding of dreams and the mind, it is essential reading for students and researchers of consciousness, dreams, philosophy and cognitive sciences, as well as anyone who is curious about dreaming.

A renowned philosopher of the mind, also known for his groundbreaking work on Buddhism and cognitive science, Evan Thompson combines the latest neuroscience research on sleep, dreaming, and meditation with Indian and Western philosophy of the mind, casting new light on the self and its relation to the brain. Thompson shows how the self is a changing process, not a static thing. When we are awake we identify with our body, but if we let our mind wander or daydream, we (...) project a mentally imagined self into the remembered past or anticipated future. As we fall asleep, the impression of being a bounded self distinct from the world dissolves, but the self reappears in the dream state. If we have a lucid dream, we no longer identify only with the self within the dream. Our sense of self now includes our dreaming self, the "I" as dreamer. Finally, as we meditate--either in the waking state or in a lucid dream--we can observe whatever images or thoughts arise and how we tend to identify with them as "me." We can also experience sheer awareness itself, distinct from the changing contents that make up our image of the self. Contemplative traditions say that we can learn to let go of the self, so that when we die we can witness its dissolution with equanimity. Thompson weaves together neuroscience, philosophy, and personal narrative to depict these transformations, adding uncommon depth to life's profound questions. Contemplative experience comes to illuminate scientific findings, and scientific evidence enriches the vast knowledge acquired by contemplatives. (shrink)

The paradigmatic assumption that REM sleep is the physiological equivalent of dreaming is in need of fundamental revision. A mounting body of evidence suggests that dreaming and REM sleep are dissociable states, and that dreaming is controlled by forebrain mechanisms. Recent neuropsychological, radiological, and pharmacological findings suggest that the cholinergic brain stem mechanisms that control the REM state can only generate the psychological phenomena of dreaming through the mediation of a second, probably dopaminergic, forebrain mechanism. The latter mechanism (and thus (...) dreaming itself) can also be activated by a variety of nonREM triggers. Dreaming can be manipulated by dopamine agonists and antagonists with no concomitant change in REM frequency, duration, and density. Dreaming can also be induced by focal forebrain stimulation and by complex partial (forebrain) seizures during nonREM sleep, when the involvement of brainstem REM mechanisms is precluded. Likewise, dreaming is obliterated by focal lesions along a specific (probably dopaminergic) forebrain pathway, and these lesions do not have any appreciable effects on REM frequency, duration, and density. These findings suggest that the forebrain mechanism in question is the final common path to dreaming and that the brainstem oscillator that controls the REM state is just one of the many arousal triggers that can activate this forebrain mechanism. The “REM-on” mechanism (like its various NREM equivalents) therefore stands outside the dream process itself, which is mediated by an independent, forebrain “dream-on” mechanism. Key Words: acetylcholine; brainstem; dopamine; dreaming; forebrain; NREM; REM; sleep. (shrink)

The conscious experiences we have during sleep have the potential to improve our empathetic response to those who experience delusions and psychosis by supplying a virtual reality simulation of mental illness. Empathy for those with mental illness is lacking and there has been little improvement in the last decades despite efforts made to increase awareness. Our lack of empathy, in this case, may be due to an inability to accurately mentally simulate what it’s like to have a particular cognitive disorder. (...) Dreaming can help mitigate these deficits by placing the dreamer directly into a realistic virtual simulation and thus increase their capacity for empathy. Increasing empathy would go some way towards reducing the stigma and discrimination faced by people in this group. Recent work suggests that virtual reality can increase empathy towards a variety of marginalised groups, however, this technology is limited in its ability to simulate mental illnesses such as delusions. Dreams, however, are at times virtual reality delusion simulators. They can replicate, to a reasonable degree, delusions and psychosis, and through these experiences, we can learn ‘what it’s like’ to have these conditions. It is essential that we recognise these experiences for what they are, attempt to remember and reflect on them. Instead of disregarding dreams due to their unusualness and bizarreness, we can learn from these experiences and expand our understanding of the human condition and its many forms. (shrink)

This edited volume is the first systematic philosophical investigation of the complex and multifarious relationships between dreaming and memory. Featuring fifteen contributions by leading researchers, it explores a range of issues that arise when dreaming and memory are considered together. What does one remember when one remembers what one dreamt, and what is it for a memory of a dream to be accurate? What are the phenomenological, cognitive, and epistemic similarities and dissimilarities between dreaming and remembering? How does the self (...) figure in dreams and memories? The book will serve as an indispensable resource both for philosophers interested in dreaming or memory and for their philosophically-minded colleagues in empirical disciplines and will provide an invaluable starting point for advanced students in need of a snapshot of the state of the art in philosophical research on dreaming and memory.

A comprehensive proposal for a conceptual framework for describing conscious experience in dreams, integrating philosophy of mind, sleep and dream research, and interdisciplinary consciousness studies. Dreams, conceived as conscious experience or phenomenal states during sleep, offer an important contrast condition for theories of consciousness and the self. Yet, although there is a wealth of empirical research on sleep and dreaming, its potential contribution to consciousness research and philosophy of mind is largely overlooked. This might be due, in part, to a (...) lack of conceptual clarity and an underlying disagreement about the nature of the phenomenon of dreaming itself. In Dreaming, Jennifer Windt lays the groundwork for solving this problem. She develops a conceptual framework describing not only what it means to say that dreams are conscious experiences but also how to locate dreams relative to such concepts as perception, hallucination, and imagination, as well as thinking, knowledge, belief, deception, and self-consciousness. Arguing that a conceptual framework must be not only conceptually sound but also phenomenologically plausible and carefully informed by neuroscientific research, Windt integrates her review of philosophical work on dreaming, both historical and contemporary, with a survey of the most important empirical findings. This allows her to work toward a systematic and comprehensive new theoretical understanding of dreaming informed by a critical reading of contemporary research findings. Windt's account demonstrates that a philosophical analysis of the concept of dreaming can provide an important enrichment and extension to the conceptual repertoire of discussions of consciousness and the self and raises new questions for future research.

This chapter works towards a better understanding of the contribution made by the state of wakeful consciousness to the stream of consciousness over time. It does this through reflection on what is missing in certain cases of non-wakeful consciousness. Granting the assumption that dreaming is a mode of perceptual imagination, the chapter contrasts perceptual imagination in the wakeful condition with perceptual imagination in dreaming sleep. It makes a suggestion about what is missing that draws on claims about the wakeful condition (...) made by Brian O’Shaughnessy. According to this suggestion, what is missing is the occurrence of intentional mental action accompanied by non-inferential self-awareness. Building on a critique of O’Shaughnessy’s discussion, the chapter develops a ‘Capacitation Thesis’ about wakeful consciousness, according to which wakefulness is a state of being capacitated with respect to a range of relevant capacities. Imagination in the dream is discussed in the light of this thesis. (shrink)

The aim is to discover a principle governing the formation of the dream. Now dreaming has an analogy with consciousness in that it is a seeming-consciousness. Meanwhile consciousness exhibits a tripartite structure consisting of understanding oneself to be situated in a world endowed with given properties, the mental processes responsible for the state, and the concrete perceptual encounter of awareness with the world. The dream analogues of these three elements are investigated in the hope of discovering the source of the (...) kinship between dream and consciousness. The dream world proves to be a logically impossible world, limited by nothing more than sheer narratability. The internal world of the dreamer is notable for the limitlessness of the scope allotted to the imagination, together with the presence of two important phenomena encountered in waking consciousness: a measure of interiority, and the positing of a world. Finally, the dream further replicates consciousness in so far as we seem in dreaming concretely to experience our physical surrounds in the form of perceptual imagining. These properties play their part in enabling the dream to be a seeming-consciousness. At the same time they are such as to necessitate its not being consciousness. It is proposed that in the light of these properties, and those composing the state of consciousness, the dream simply is the imagining of consciousness. (shrink)

We tested the new threat simulation theory of the biological function of dreaming by analysing 592 dreams from 52 subjects with a rating scale developed for quantifying threatening events in dreams. The main predictions were that dreams contain more frequent and more severe threats than waking life does; that dream threats are realistic; and that they primarily threaten the Dream Self who tends to behave in a relevant defensive manner in response to them. These predictions were confirmed and the theory (...) empirically supported. We suggest that the threat simulation theory of dreaming may have wider implications for theories about the function of consciousness. (shrink)

Dreaming is often characterized as lacking high-order cognitive skills. In two studies, we test the alternative hypothesis that the dreaming mind is highly similar to the waking mind. Multiple experience samples were obtained from late-night REM sleep and waking, following a systematic protocol described in Kahan . Results indicated that reported dreaming and waking experiences are surprisingly similar in their cognitive and sensory qualities. Concurrently, ratings of dreaming and waking experiences were markedly different on questions of general reality orientation and (...) logical organization . Consistent with other recent studies , experiences sampled from dreaming and waking were more similar with respect to their process features than with respect to their structural features. (shrink)

What is it like to dream? On an orthodox view, dreams involve misleading sensations and false beliefs. I argue, on philosophical, psychological, and neurophysiological grounds, that orthodoxy about dreaming should be rejected in favor of an imagination model of dreaming. I am thus in partial agreement with Colin McGinn, who has argued that we do not have misleading sensory experiences while dreaming, and partially in agreement with Ernest Sosa, who has argued that we do not form false beliefs while dreaming. (...) Rather, on my view, dreams involve mental imagery and propositional imagination. I defend the imagination model of dreaming from objections. (shrink)

Dreams are often defined as sleeping experiences with phenomenal character similar to perceptions of the real world. Hence they pose a prima facie challenge to accounts of phenomenal character in terms of acquaintance relations. One response is disjunctivist: to give a different account of their phenomenal character from that of successful perceivings. I argue that, given the alleged frequency of dreaming on the standard model, this disjunctivist approach weakens the explanatory value of the acquaintance account of the phenomenal character of (...) successful perceivings. Another response is to follow Malcolm and Dennett in denying that dreaming has phenomenal character at all. I present a cultural-social model of dreams and argue that we lack theory-neutral evidence of the phenomenal character of dreams and thus it is legitimate to choose between theories of dreaming on the basis of their fit with our best theory of the phenomenal character of successful perceivings, namely acquaintance.

: The central aim of this paper is to offer a historical reconstruction of phenomenological studies on dreaming and to put forward a draft for a phenomenological theory of the dream state. Prominent phenomenologists have offered an extremely valuable interpretation of the dream as an intentional process, stressing its relevance in understanding the complexity of the mental life of subject, the continuous interplay between reality and unreality, and the possibility of building parallel spheres of experience influencing the development of personal (...) identity. Taking into consideration the main characteristics of dream experience emphasized by these scholars, in the final part of the paper I propose to elaborate a new phenomenology of dreaming, which should be able to offer a theoretical description of dream states. My sketched proposal is based on Eugen Fink’s notion of the dream as “presentification”. By combining the past and the present of phenomenological investigation, I aim at suggesting a philosophical framework to explain the intentional features of dreaming as Erlebnis. Keywords : Phenomenology; Dreaming State; Presentification; Erlebnis; Ego La coscienza sognante: un contributo dalla fenomenologia Riassunto : Lo scopo principale di questo articolo è offrire una ricostruzione storica degli studi fenomenologici sul sogno e proporre un abbozzo per una teoria fenomenologia dello stato onirico. Importanti fenomenologi hanno offerto un’interpretazione particolarmente valida del sogno inteso come processo intenzionale, mettendone in rilievo il significato per la comprensione della complessità della vita mentale del soggetto, la continua interazione tra realtà e irrealtà, e la possibilità di costruire sfere parallele di esperienza che esercitano un’influenza sull’identità personale. Prendendo in considerazione le principali caratteristiche dell’esperienza onirica messe in luce da questi studiosi, nella parte finale dell’articolo propongo di elaborare una nuova fenomenologia del sogno, che dovrebbe essere in grado di offrire una descrizione teoretica degli stati onirici. Il mio abbozzo di proposta si basa sulla nozione di “presentificazione” di Eugen Fink. Mettendo insieme il passato e il presente dell’indagine fenomenologica, il mio obiettivo è proporre una cornice filosofica per chiarire le strutture intenzionali del sogno inteso come Erlebnis. Parole chiave : Fenomenologia; Stato onirico; Presentificazione; Erlebnis; Ego. (shrink)

In this chapter, I examine the relevance of the philosophical use of dreaming for the examination of the thesis that knowledge is perception. I begin by studying the position attributed to Protagoras in Plato’s Theaetetus, according to which the perceptual experiences we have when dreaming count as knowledge. I argue that this position requires two different subjects in the two different contexts of cognition (dreaming and waking). I suggest that Vasubandhu’s use of dreaming in the Twenty Verses — to show (...) that perception without external objects is possible — can help make sense of Protagorean perception. I raise the problem that both positions struggle to align their metaphysics with the phenomenology of perception. With the help of dreaming, Vasubandhu can explain how transformation may yield perceptual knowledge (in the form of buddha-vision). No such transformation is possible for a Protagorean, because the different subjects inhabiting different cognitive contexts are not causally related. (shrink)

Lucid dreaming provides a test case for theories of dreaming. For example, whether or not “loss of self-reflective awareness” is characteristic of dreaming, it is not necessary to dreaming. The fact that lucid dreamers can remember to perform predetermined actions and signal to the laboratory allows them to mark the exact time of particular dream events, allowing experiments to establish precise correlations between physiology and subjective reports, and enabling the methodical testing of hypotheses. [Hobson et al.; Solms].

In Dreaming Souls, Owen Flanagan provides both an accessible survey of the latest research on sleep and dreams and a compelling new theory about the nature and function of dreaming. Flanagan argues that while sleep has a clear biological function and adaptive value, dreams are merely side effects, 'free-riders', irrelevant from an evolutionary point of view. But dreams are hardly unimportant. Indeed, Flanagan argues that dreams are self-expressive, the result of our need to find or create meaning, even when we (...) are sleeping. (shrink)

We argue that the rapid eye movement dream experiences owe their structure and meaning to inherent self-organizing properties of the brain itself. Thus, we offer a common meeting ground for brain based studies of dreaming and traditional psychological dream theory. Our view is that the dreaming brain is a self-organizing system highly sensitive to internally generated influences. Several lines of evidence support a process view of the brain as a system near the edge of chaos, one that is highly sensitive (...) to internal influences. Such sensitivity is due to several factors. First, the dreaming brain normally gates out external input and thus operates without the stabilizing influences of external feedback. Second, the pre-frontal cortex is only minimally activated during REM sleep, and hence the brain operates with weakened volition, reduced logic, and diminished self-reflection. Third, because the neuromodulatory inhibition mechanism is turned off during REM, the brain responds spontaneously to the least provocation. In addition, the dreaming brain is also subject to powerful intermittent cholinergic stimulation which may stimulate creative patterns of dream activity. (shrink)

In this paper, I discuss the relationship between bodily experiences in dreams and the sleeping, physical body. I question the popular view that dreaming is a naturally and frequently occurring real-world example of cranial envatment. This view states that dreams are functionally disembodied states: in a majority of dreams, phenomenal experience, including the phenomenology of embodied selfhood, unfolds completely independently of external and peripheral stimuli and outward movement. I advance an alternative and more empirically plausible view of dreams as weakly (...) phenomenally-functionally embodied states. The view predicts that bodily experiences in dreams can be placed on a continuum with bodily illusions in wakefulness. It also acknowledges that there is a high degree of variation across dreams and different sleep stages in the degree of causal coupling between dream imagery, sensory input, and outward motor activity. Furthermore, I use the example of movement sensations in dreams and their relation to outward muscular activity to develop a predictive processing account. I propose that movement sensations in dreams are associated with a basic and developmentally early kind of bodily self-sampling. This account, which affords a central role to active inference, can then be broadened to explain other aspects of self- and world-simulation in dreams. Dreams are world-simulations centered on the self, and important aspects of both self- and world-simulation in dreams are closely linked to bodily self-sampling, including muscular activity, illusory own-body perception, and vestibular orienting in sleep. This is consistent with cognitive accounts of dream generation, in which long-term beliefs and expectations, as well as waking concerns and memories play an important role. What I add to this picture is an emphasis on the real-body basis of dream imagery. This offers a novel perspective on the formation of dream imagery and suggests new lines of research. (shrink)

Norman Malcolm wrote:That something is implausible or Impossible does not go to show that I did not dream it. In a dream I can do the impossible in every sense of the word.Malcolm nowhere suggests why this remark should be regarded as true. Indeed, many philosophers would regard it is palpably false. After all, it is not at all obvious that one can hope for, intend to do, or believe what is in every sense of the word, impossible. I think, (...) however, that Malcolm's observation is correct; and this paper is devoted to showing why it is correct. In the concluding section I present an account of dreaming that shows why it is that impossible dreams are possible.“What can a person dream?” This is an odd query; and what it might mean to put this question is not at all transparent. It is not like asking what a person might dream, when this is understood as a request for what someone is likely to dream, or what one may reasonably expect someone to dream, say, on the evening of a day in which one had visited a dentist.

Our eyes, bodies, and perspectives are constantly shifting as we observe the world. Despite this, we are very good at distinguishing between self-caused visual changes and changes in the environment: the world appears mostly stable despite our visual field moving around. This, it seems, also occurs when we are dreaming. As we visually investigate the dream environment, we track moving objects with our dream eyes, examine objects, and shift focus. These movements, research suggests, are reflected in the rapid movements or (...) saccades of our sleeping eyes. Do we really see the dream world in the same way that we see the real world? If we do, how could dreaming, usually assumed to be mind-generated hallucinations, replicate such an experience? This problem would be deflated if dreams are not hallucinations at all, but rather imagination, illusion or simply unrealistic. I argue that imagination and illusion views do not satisfactorily explain away the problem of vision and action in sleep. The imagination model is not a complete description of dreaming that is consistent with empirical research, and it is unlikely that the visual dream world is an illusion. Given that the dreaming visual experience is most likely active, hallucinatory, and at times a realistic world simulation, there are important implications for our understanding of visual perception and its relationship to movement. Evidence suggests that our dream eyes investigate the dream world as our waking eyes investigate the waking world. If changes to the unconsciously generated dream environment are perceived as external and unintentional while dream body movements are perceived as self-generated and intentional, current theory of visual perception may have to be expanded to account for how the dreaming mind generates a stable world in which we track and visually explore mind-generated objects.

This book explores what we can learn about two fascinating mental states, dreaming and memory, by investigating them in tandem. This brings to the surface several issues about the phenomena which are not apparent when we think about each in isolation. The 15 contributions are arranged into three parts: Part I: Remembering Dreams; Part II: Remembering Within Dreams; and Part III: Remembering and Dreaming Compared. The authors apply a range of methodologies: philosophical, exegetic, experimental, and formal.

Lucid dreaming refers to a dream state characterized by the dreamers awareness of being in a dream and being able to volitionally control its content. The aim of this study was to find neurophysiological evidence for the 7 criteria of lucid dreaming proposed by Paul Tholey. Each of the criteria was analyzed separately with regard to its underlying neurocircuits. We hypothesized that not one, but many regions are involved in the state of lucid dreaming. Our results have shown a satisfactory (...) overlap of the theoretical components and the brain regions activated during a lucid dream. During lucid dreaming, a brain network seems to emerge, that is more than the sum of its parts. Further research is needed to understand the psychoneurological underpinnings of lucid dreams.

"An accessible survey of the latest research on sleep and dreams and a compelling new theory about the nature and function of dreaming."--Jacket.

The studies reported in the following articles are aimed at providing a comprehensive, detailed, and quantitative picture of cognition in human dreaming. Our main premises are that waking, REM sleep, and non-REM sleep represent physiologically distinct and identifiable brain states and that the differences between waking, REM, and NREM mentation reflect these physiological differences. We have studied dreams at a formal level of analysis and, in these papers, have studied the specific dream properties of emotions, bizarre transformations, scene shifts, and (...) plot coherence, in adults and 4- to 10-year-old children, as part of a larger effort to map state-dependent mental phenomena back onto the varying neurobiological processes that must underlie them. We believe that such efforts will enhance our understanding not only of dreaming and its neurophysiological substrates, but also of the cognitive processes that dreaming shares with other unusual mental states.

The paper puts forward a criterion for distinguishing remembering from imagining and dreaming. The idea is that a state of imagining qualifies as remembering, not dreaming, if it is underwritten by a cognitive mechanism whose proper function it is to track the truth. The hallmark of states of dreaming is that they aim at something other than truth, such as verisimilitude or interestingness.

Evidence of reflective awareness and metacognitive monitoring during REM sleep dreaming poses a significant challenge to the commonly held view of dream cognition as necessarily deficient relative to waking cognition. To date, dream metacognition has not received the theoretical or experimental attention it deserves. As a result, discussions of dream cognition have been underrepresented in theoretical accounts of consciousness. This paper argues for using a converging measures approach to investigate the range and limits of cognition and metacognition across the sleep–wakefulness (...) cycle. The paradigm developed by LaBerge and his colleagues to study "lucid-control" dreaming offers one such framework for relating phenomenological, cognitive, and physiological measures. In a lucid-control dream, the dreamer is both aware that the experimental context is a dream and has the ability to intentionally regulate aspects of the dream . Subjects can make patterns of deliberate eye movements to signal from the dream and thus index significant events such as the time of lucidity onset and the completion of previously agreed-upon tasks in the dream. Lucid dreaming and other examples of reflective awareness during dreaming have important implications for models of human cognition. The existence of these phenomena raises fundamental questions about current assumptions regarding "state" constraints on consciousness and cognition. (shrink)

Lucid dreams are dreams in which a person becomes aware that they are dreaming. They are different from ordinary dreams, not just because of the dreamer's awareness that they are dreaming, but because lucid dreams are often strikingly realistic and may be emotionally charged to the point of elation. Celia Green and Charles McCreery have written a unique introduction to lucid dreams that will appeal to the specialist and general reader alike. The authors explore the experience of lucid dreaming, relate (...) it to other experiences such as out-of-the-body experiences (to which they see it as closely related) and apparitions, and look at how lucid dreams can be induced and controlled. They explore their use for therapeutic purposes such as counteracting nightmares. Their study is illustrated throughout with many case histories. (shrink)

This special issue unites original theoretical and empirical research on two topics that are gaining traction in cognitive neuroscience and psychology, but so far have small philosophical footprints: dreaming and waking mind wandering. While the fields of dream and mind wandering research are largely separate, phenomenological and neurophysiological similarities between waking mind wandering and sleep-related experiences suggest that these phenomena are intimately connected. Together, they raise important questions about the nature and functions of spontaneous mental phenomena and their relation to (...) wakefulness and sleep, as well as for theories of attention, action, and consciousness.

Dreaming can provide a marvelous opportunity for the “playful” exploration of dramatic events. But the chance to learn to deal with danger is only a small part of it. More important is the chance to discover what it is like to be the subject of strange but humanly significant mental states. [Revonsuo].

"Dreaming with open eyes" is a tagline for Spinoza's critique of Descartes; the dreams in question are principally those of volition and the active imagination. In this article, I compare the Cartesian theory of imagination as an active, but not fully rational, power of the mind and the Cartesian account of the volitional self to Spinoza's views. Descartes's own dreams and theories of dreaming are the focus of the first part of the article. Thereafter I examine Spinoza's critique of Descartes (...) and his alternative account of imagination. Finally, I argue that there is a positive sense of dreaming with open eyes to be recuperated in Spinoza's thought. Construed positively, to dream with open eyes is to understand dreams and imagination as natural phenomena and so to be able to respond constructively to them in ethical and political, as well as epistemological, life.

Since the discovery that the characteristics of dreaming sleep are far stronger in Stage 1 rapid eye movement sleep than in any other biological state, investigators have attempted to determine the relative responsibility of the tonic versus the phasic properties of REM sleep for the different characteristics of dreaming–features such as the amount of information in the dream report, the brightness and clarity of the visual images, shifts in thematic continuity, and incongruities of image and meaning. The present experiment is (...) designed to identify dream characteristics that are specifically associated with tonic changes in level of cortical activation within sleep. It samples reports of imagery and thought during spontaneous variations within one phase of the 24-h diurnal rhythm and across the REM-NREM sleep cycle in order to identify the independent and joint contributions of the two cycles to imagery and thought. The rising phase of the diurnal cycle in the late night and morning was estimated from clock time during the late night and early morning and was varied by delaying the sleep onset and waking time of the subjects. Considered together with other studies, the results suggest that the major determinant of vivid visual imagery and enhanced cognitive activity during sleep is a pattern of subcortical and cortical activation that is common to both the REM phase of the REM-NREM cycle and the activated phase of the 24-h diurnal wake-sleep cycle.

A familiar anti-sceptical response (à la Sosa) to radical sceptical scenarios employs the safety of knowledge. Radical sceptical scenarios are purported to be too modally remote to really threaten knowledge of ordinary propositions. Why? Because knowledge requires safety, and safety requires the target belief to be true in all nearby possible worlds, but radical sceptical scenarios purportedly take place at distant possible worlds. Hence, the safety theorist claims that radical sceptical scenarios don’t challenge our knowledge of ordinary propositions. But it's (...) alleged by Sosa and others that there's one radical sceptical scenario that can’t be dismissed so easily: the dream scenario. After all, unlike evil demons and brains in vats, ‘dreaming is a daily part of our lives…it is too close for comfort’. In this paper, I sketch an argument to the effect that there's good reason to think that the dream of dream scepticism describes a modally remote possibility, in which case I argue that if the safety-based anti-sceptical response is successful against the evil demon sceptical scenario, the brain in a vat sceptical scenario, and other Cartesian sceptical scenarios in this mould, then it's successful against the dream sceptical scenario as well.

Sleep and dreaming are important daily phenomena that are receiving growing attention from both the scientific and the philosophical communities. The increasingly popular predictive brain framework within cognitive science aims to give a full account of all aspects of cognition. The aim of this paper is to critically assess the theoretical advantages of Predictive Processing (PP, as proposed by Clark 2013, Clark 2016; and Hohwy 2013) in defining sleep and dreaming. After a brief introduction, we overview the state of the (...) art at the intersection between dream research and PP (with particular reference to Hobson and Friston 2012; Hobson et al. 2014). In the following sections we focus on two theoretically promising aspects of the research program. First, we consider the explanations of phenomenal consciousness during sleep (i.e. dreaming) and how it arises from the neural work of the brain. PP provides a good picture of the peculiarity of dreaming but it can’t fully address the problem of how consciousness comes to be in the first place. We propose that Integrated Information Theory (IIT) (Oizumi et al. 2014; Tononi et al. 2016) is a good candidate for this role and we will show its advantages and points of contact with PP. After introducing IIT, we deal with the evolutionary function of sleeping and dreaming. We illustrate that PP fits with contemporary researches on the important adaptive function of sleep and we discuss why IIT can account for sleep mentation (i.e. dreaming) in evolutionary terms (Albantakis et al. 2014). In the final section, we discuss two future avenues for dream research that can fruitfully adopt the perspective offered by PP: (a) the role of bodily predictions in the constitution of the sleeping brain activity and the dreaming experience, and (b) the precise role of the difference stages of sleep (REM (Rapid eye movement), NREM (Non-rapid eye movement) in the constitution and refinement of the predictive machinery.

Having fascinated some of the greatest philosophers from the earliest times, dreaming figures importantly in the history of philosophy, as in Plato’s Theaetetus, Augustine’s Confessions, and, perhaps most famously, Descartes’s Mediations. By far the greatest philosophical focus on dreaming has been epistemic: Socrates suggests to Theaetetus that since he cannot tell whether he is dreaming, he cannot trust his senses to know contingent facts about the world around him. And a similar worry drives Descartes’s radical doubt in the First Meditation. (...) We might think that dream skepticism is, among the radical Cartesian skeptical scenarios, a particularly worrying one, since dreams, unlike evil demons, are a commonplace of everyday life. (shrink)

What is dreaming, and what causes it? Why are dreams so strange, and why are they so hard to remember? Replacing dream mystique with modern dream science, J. Allan Hobson provides a new and increasingly complete picture of how dreaming is created by the brain. Dreaming explores how the new science of dreaming is affecting theories in psychoanalysis, and how it is helping our understanding of the causes of mental illness. Through an investigation of his own dreams to illustrate and (...) explain some of the fascinating discoveries of modern sleep science, Hobson challenges some of the traditionally accepted theories about the meaning of dreams and reveals why sleep is not just good for health but essential for life.

Aphantasia is a recently discovered disorder characterised by the total incapacity to generate visual forms of mental imagery. This paper proposes that aphantasia raises important theoretical concerns for the ongoing debate in the philosophy and sci- ence of consciousness over the nature of dreams. Recent studies of aphantasia and its neurobehavioral correlates reveal that the ma- jority of aphantasics, whilst unable to produce visual imagery while awake, nevertheless retain the capacity to experience rich visual dreams. This finding constitutes a novel (...) explanandum for theories of dreaming. Specifically, I argue that the recent dream reports of aphantasics constitute an empirical challenge to the emerging family of views which claim that dreams are essentially imaginative ex- periences, constitutively involving the kinds of mental imagery which aphantasics, ex-hypothesi, lack. After presenting this challenge in the context of Jonathan Ichikawa’s recent arguments for this view, I argue that this empirical challenge may be overcome if the ima- gination theorist abandons Ichikawa’s account of dreaming in favour of a modified version. This involves the claim that dreams are essentially inactive and constitutively involve non voluntary forms of imagination. I conclude with a suggestion for further research which can test the viability of this alternative hypothesis, and move the debate forward. (shrink)

_Dreaming the Myth Onwards_ shows how a revised appreciation of myth can enrich our daily lives, our psychological awareness, and our human relationships. Lucy Huskinson and her contributors explore the interplay between myth, and Jungian thought and practice, demonstrating the philosophical and psychological principles that underlie our experience of psyche and world. Contributors from multi-disciplinary backgrounds throughout the world come together to assess the contemporary relevance of myth, in terms of its utility, its effectual position within Jungian theory and practice, (...) and as a general approach for making sense of life. As well as examining the more conscious facets of myth, this volume discusses the unconscious psychodynamic "processes of myth", including active imagination, transference, and countertransference, to illustrate just how these mythic phenomena give meaning to Jungian theory and therapeutic experience. This rigorous and scholarly analysis showcases fresh readings of central Jungian concepts, updated in accordance with shifts in the cultural and epistemological concerns of contemporary Western consciousness. _Dreaming the Myth Onwards_ will be essential reading for practicing analysts and academics in the field of the arts and social sciences.

I argue that being wide awake is an epistemic virtue which enables me to recognize immediately that I'm wide awake. Also I argue that dreams are imaginings and that the wide awake mind can immediately discern the difference between imaginings and vivid sense experience. Descartes need only pinch himself.

Activity in the prefrontal cortex may distinguish the meta-awareness experienced during lucid dreams from its absence in normal dreams. To examine a possible relationship between dream lucidity and prefrontal task performance, we carried out a prospective study in 28 high school students. Participants performed the Wisconsin Card Sort and Iowa Gambling tasks, then for 1 week kept dream journals and reported sleep quality and lucidity-related dream characteristics. Participants who exhibited a greater degree of lucidity performed significantly better on the task (...) that engages the ventromedial prefrontal cortex, but degree of lucidity achieved did not distinguish performance on the task that engages the dorsolateral prefrontal cortex, nor did it distinguish self-reported sleep quality or baseline characteristics. The association between performance on the Iowa Gambling Task and lucidity suggests a connection between lucid dreaming and ventromedial prefrontal function. (shrink)

Dreaming is a communicative activity between the most sensitive archive of the enregistered experience of life on the earth, the brain, and the most plastic medium for the discovery and practice of meaning, the mind or culture. Both love and war have been made on the basis of dreams, not to mention scientific discoveries. In ancient Greece dreams were medicinal parts of curative sleeping or "incubation" rites in the temple of Aesculapius, and many psychoanalytic physicians today still consider dreams as (...) possessing therapeutic potential. The ethnographic literature gives ample testimony to the great significance accorded to dreams by all of the world cultures. Dreams form a rich store of ethnographic evidence, and their indigenous interpretations can often illuminate the central issues and conflicts of a people otherwise hidden from obvious view. Given these facts, plus the physiological facts that the dream process itself involves deeply-rooted material brain functions, and that rapid eye movement, or REM, sleep, which is the key indicator of human dreaming, is shared by all mammals, it remains strange how little attention is given to dreaming as a formative aspect of human evolution and culture. -/- This essay addresses dreaming as a formative aspect of human evolution and culture by viewing dreaming as a borderland between biology and culture, a thoroughly social, yet private experience. Dreaming not only highlights the "cultic" roots of culture—the spontaneous impulse to meaning—but also illustrates one of the ways in which the technics of the biosocial human body itself form the primary source of culture. I show why dreaming, although private, is a thoroughly cultural, biological, communicative activity. -/- Culture and biology are often treated by social scientists as though they were oil and water, not to be mixed. I should inform the culture theorist at the start that I am fully aware of the assumed nature-culture dichotomy, and that I reject it. I do so not because I am a sociobiologist, quite the contrary, rather because I am a semiotician, and my studies of signs have led me toward a critical reconstruction of the concepts of nature and culture. In what follows I beg the reader's patience, since I will draw from diverse materials and project some speculative hypotheses in places in order to make my argument. -/- . (shrink)

The five papers in this issue all deal with the proper evolutionary function of sleep and dreams, these being different. To establish that some trait of character is an adaptation in the strict biological sense requires a story about the fitness enhancing function it served when it evolved and possibly a story of how the maintenance of this function is fitness enhancing now. My aim is to evaluate the proposals put forward in these papers. My conclusion is that although sleep (...) is almost certainly an adaptation, dreaming is not.
