Sleepwalking, also known as somnambulism, occurs most commonly during stage 3 or stage 4 NREM sleep. These stages are characterized by slow wave sleep which is the deepest stage of non-REM sleep. It is unlikely to occur during stage 1 or 2 NREM sleep, as they are lighter stages of sleep, and it is impossible to happen during REM sleep as the muscles are temporarily paralyzed.
