Verified step by step guidance1
Understand the different stages of the sleep cycle: Non-REM stage 1 (light sleep), Non-REM stage 3 (deep sleep), REM sleep, and the transition from wakefulness to sleep.
Recognize that somnambulism, or sleepwalking, is a parasomnia, which typically occurs during deep sleep rather than lighter sleep stages or REM sleep.
Recall that Non-REM stage 3 is also known as slow-wave sleep or deep sleep, characterized by slow brain waves and minimal muscle activity.
Note that parasomnias like sleepwalking are most common during Non-REM stage 3 because the brain is in a deep, restorative state but motor pathways can still be active.
Conclude that somnambulism most commonly occurs during Non-REM stage 3 (deep sleep).
