Sleep walking is a real disorder that’s most common in children but it can also happen to adults. Some sleep walkers actually eat while they sleep, which has been well documented. Walking in your sleep can be dangerous because you can fall down the stairs, walk outside, or even climb out of windows. If you encounter a sleepwalker you should gently try to guide them back to their bed. If the problem persists, there is help available in the form of medications and hypnosis. If the sleep walking is being triggered by a medical or other problem like sleep apnea, then treatment is typically geared toward the underlying cause.
