Sleepwalking, also known as somnambulism, occurs during NREM Stage 4 sleep, which is the deepest stage of non-REM sleep. During this stage, the brain is less responsive to external stimuli and the body is in a state of low muscle tone, making it easier to move around without waking up. Sleepwalking is uncommon during REM sleep because the body is typically paralyzed during this stage to prevent acting out dreams.
