Just?

Is your your brain setting your body down to bed? Your bed setting your body down to sleep? Do you have free will, or are we little automatons in a closed, predictable system?

Why does resting my brain take my brain to another world without my body?

…just… 🙄

You don’t also escape into the unseen, transform into a beautiful butterfly, and frolic through the planes?

It’s more shutting down so your cells can repair all the drinking and fast food you ate.
