Sleepwalking usually occurs early in the night — often one to two hours after falling asleep. It's unlikely to occur during naps. A sleepwalking episode can occur rarely or often, and an episode generally lasts several minutes, but can last longer. Someone who is sleepwalking may: 
Get out of bed and walk around
Sit up in bed and open his or her eyes
Have a glazed, glassy-eyed expression
Not respond or communicate with others
Be difficult to wake up during an episode
Be disoriented or confused for a short time after being awakened
Not remember the episode in the morning
Have problems functioning during the day because of disturbed sleep
Have sleep terrors in addition to sleepwalking
 Sometimes, a person who is sleepwalking will: 
Do routine activities, such as getting dressed, talking or eating
Leave the house
Drive a car
Engage in unusual behavior, such as urinating in a closet
Engage in sexual activity without awareness
Get injured, for example, by falling down the stairs or jumping out a window
Become violent during the period of brief confusion immediately after waking or, occasionally, during sleepwalking
 When to see a doctor Occasional episodes of sleepwalking aren't usually a cause for concern and typically resolve on their own. You can simply mention the sleepwalking at a routine physical or well-child exam. However, consult your doctor if the sleepwalking episodes: 
Occur often — for example, more than one to two times a week or several times a night
Lead to dangerous behavior or injury to the person who sleepwalks or to others
Cause significant sleep disruption to household members or the person who sleepwalks
Result in daytime symptoms of excessive sleepiness or problems functioning
Start for the first time as an adult
Continue into your child's teen years
