Both somnambulism and somnambulism are forms of ambulatory automatism: a specific form of the hazy state. It is characterized by the absence of hallucinations, delusions and mood changes. Patients may perform purposeless actions that are inappropriate to their environment or even meaningless when they are unconscious. For example, wandering around the room and outside without any purpose; performing simple daily activities such as opening and closing the door in a stereotypical manner. The movements start suddenly, last briefly and disappear suddenly, and are forgotten afterwards. There are two types of sleepwalking disorder (somnambulism): also known as sleep walking disorder and nocturnal wandering disorder. Patients mostly have episodes during sleep or one to two hours after falling asleep. The patient does not wake up, but suddenly gets up and performs some simple, purposeless actions, such as walking back and forth in the room or doing some simple labor activities, and after a few minutes of seizure, the patient goes to bed and falls asleep quietly, and wakes up the next morning and completely forgets. It is mostly seen in epilepsy, but also in hysteria and normal children. Fugue: Most often occurs during the day or suddenly after waking up in the morning. The patient wanders aimlessly or travels abroad, enters unfamiliar dwellings, or breaks into forbidden areas, and may give away clothes and money to others. It usually lasts for several hours or days and then suddenly wakes up with partial recall of the seizure. Most often seen in epilepsy, status reactive, hysteria and after craniocerebral injury.
