The term 'Sleepwalker' is often used to describe someone who engages in a behavior known as somnambulism, or sleepwalking. Somnambulism is a disorder in which a person gets up and moves around during sleep without being aware of their actions. It is a common sleep disorder that can occur in both adults and children. Symptoms of sleepwalking include walking around while asleep, talking or mumbling while asleep, and having difficulty waking up from sleep. Treatment for sleepwalking usually involves lifestyle changes such as avoiding alcohol and caffeine before bedtime, getting enough sleep, and avoiding stressful situations.
