Sleepwalking (or somnambulism) is a behavioral sleep disorder that causes people to walk or perform other activities while asleep.
Episodes of sleepwalking typically happen during deep sleep, or during the transition from deep sleep to a lighter stage. It’s not associated with REM (rapid eye movement) sleep, as during that stage your body is effectively paralyzed.
It can be very difficult to wake up a sleepwalker, since they typically remain in deep sleep throughout the duration of the episode. This also means most sleepwalkers have very little memory of what they were when awoken.
