How does the sleeping brain retain the intentions of a person’s conscious self (like not moving all or part of the body, or waking at a very specific time) and then actually carry them out?
In: Biology
During actual dream sleep (R.E.M.) however, your brain paralyzes your body so you don’t act out your dream activities and accidentally kill yourself.
This would then mean that sleep walking doesn’t generally happen during dream sleep.
It also explains that rare but unsettling experience of waking up and not being able to move. This can include visual dream hallucinations as well which can explain many ghost and alien sightings that occur in bed.
This fusion of the waking and sleeping state is called hypnagogia
