Somnambulism is the technical term used to describe sleepwalking. Sleepwalking is a type of arousal parasomnia, or abnormal sleep activity. While often associated with childhood, sleepwalking may occur at any age. During somnambulism, an individual may appear to be fully awake, with eyes open, but is not aware of his or her actions.

SureHire explains somnambulism

Somnambulism, or sleepwalking, as the name implies, is characterized by physical movement while sleeping. Because sleepwalkers are unaware of their behavior and surroundings, sleepwalking can be dangerous. During an episode of somnambulism, the sleepwalker may be difficult to awaken and disoriented even after awakening. In extreme instances, sleepwalkers have been known to leave their homes and even operate motor vehicles. Individuals who suffer from frequent bouts of sleepwalking may experience daytime sleepiness and other symptoms of sleep deprivation.
