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]
Movement disorders Hypokinetic movement disorders refer to akinesia (lack of movement), hypokinesia (reduced amplitude of movements), bradykinesia (slow movement) and rigidity. In primary movement disorders, the abnormal movement is the primary manifestation of the disorder. In secondary movement disorders, the abnormal movement is a manifestation of another systemic or neurological disorder.[3]
