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]
Rheum When the individual is awake, blinking of the eyelid causes rheum to be washed away with tears via the nasolacrimal duct. The absence of this action during sleep, however, results in a small amount of dry rheum accumulating in corners of the eye, most notably in children.[citation needed]
