Sleep paralysis is a temporary inability to move or speak that occurs when you're waking up or falling asleep. It's not harmful and should pass in a few seconds or minutes, but can be very frightening.
Although there may be certain triggers, ultimately sleep paralysis is believed to be a problem with the regulation of REM. During this phase of sleep, the body is kept relaxed so that dreams are not acted out. If this relaxation, or atonia, occurs while the person is awake, it can cause temporary paralysis. This may be experienced when a REM period is disrupted.
