Somnambulist: meaning, definitions and examples

sleepwalking

A somnambulist is a person who sleepwalks, engaging in activities while in a state of sleep. This phenomenon occurs during slow-wave sleep, where the individual may walk, talk, or perform other complex behaviors without awareness. Somnambulism is more common in children, but it can also affect adults. Often, somnambulists do not remember their actions upon waking. It is sometimes triggered by stress, sleep deprivation, or certain medications.
