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]
Delayed sleep phase disorder Delayed sleep phase disorder (DSPD), more often known as delayed sleep phase syndrome and also as delayed sleep-wake phase disorder, is a chronic dysregulation of a person's circadian rhythm (biological clock), compared to the general population and relative to societal norms. The disorder affects the timing of sleep, peak period of alertness, the core body temperature rhythm, and hormonal and other daily cycles. People with DSPD generally fall asleep some hours after midnight and have difficulty waking up in the morning.[1] People with DSPD probably have a circadian period significantly longer than 24 hours.[2] Depending on the severity, the symptoms can be managed to a greater or lesser degree, but no cure is known, and research suggests a genetic origin for the disorder.
