what is it called when you are sleep and can't move
Sleep paralysis Sleep paralysis is when, during awakening or falling asleep, one is aware but unable to move.[1][2] During an episode, one may hear, feel, or see things that are not there.[1] It often results in fear.[1] Episodes generally last less than a couple of minutes.[2] It may occur as a single episode or be recurrent.[1]
Dream Accumulated observation has shown that dreams are strongly associated with REM rapid eye movement sleep, during which an electroencephalogram (EEG) shows brain activity that, among sleep states, is most like wakefulness. Participant-remembered dreams during NREM sleep are normally more mundane in comparison.[50] During a typical lifespan, a person spends a total of about six years dreaming[51] (which is about two hours each night).[52] Most dreams only last 5 to 20 minutes.[51] It is unknown where in the brain dreams originate, if there is a single origin for dreams or if multiple portions of the brain are involved, or what the purpose of dreaming is for the body or mind.
