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]
Locked-in syndrome Locked-in syndrome (LIS), also known as pseudocoma, is a condition in which a patient is aware but cannot move or communicate verbally due to complete paralysis of nearly all voluntary muscles in the body except for vertical eye movements and blinking. The individual is conscious and sufficiently intact cognitively to be able to communicate with eye movements.[3] The EEG is normal in locked-in syndrome. Total locked-in syndrome, or completely locked-in state (CLIS), is a version of locked-in syndrome wherein the eyes are paralyzed as well.[4][5] Fred Plum and Jerome Posner coined the term for this disorder in 1966.[6][7]
