When Sleepwalking Happens

During the first third of sleep, your body is in non-REM - your deepest stage of sleep. Your brain quiets down and you aren't dreaming. Your body is active, and you tend to toss and turn.

People usually sleepwalk during the first third of their sleep pattern. Sleepwalking episodes can last from a few seconds to half an hour. Sleepwalkers can perform many activities, from walking around to driving a car or playing an instrument.
