The term sleepwalking does not only refer to walking but can apply to a range of behaviors, some complex, which can also include talking in one’s sleep and using the bathroom. Generally sleepwalking involves rising from bed and walking around; as with other NREM sleep arousal episodes, these are most likely to occur in the first third of the night, during slow-wave sleep.
An individual who is sleepwalking has reduced alertness and responsiveness and a blank stare. They will generally not respond to efforts by others to wake them or talk to them. If they are awakened during an episode they could be disoriented for a time, and will likely have no or limited recall for the episode, but will then experience a full recovery of cognitive function and appropriate behavior.
