The most obvious symptom is sleepwalking: movement of the body during deep sleep. This movement may be as simple as suddenly sitting up, or walking around the room or through the house. In extreme cases, people have been known to cook, or even drive, while asleep.
Sleepwalkers may also experience:
- Difficulty awakening during somnambulism
- No memory of the event
- Open eyes and blank facial expressions
- Talking, although rarely comprehensibly
- Urinating in unusual places (usually in children)
- Use of obscene language not used when awake.
