Somnambulism, commonly known as sleepwalking, is a sleep disorder characterized by walking or performing other complex behaviors while in a state of sleep. It typically occurs during the deep stages of non-REM sleep and is more prevalent in children, though it can also affect adults. Individuals who experience somnambulism may have little to no memory of their actions upon waking. While often harmless, it can pose risks if the person engages in potentially dangerous activities while asleep.
