In basic training in the Air Force, I woke up and saw a guy making his bed in the middle of the night, he was totally asleep. I also had the sleep walking disorder, one time going all the way to work in the middle of the night to have my sergeant ask me what are you doing here Newport? Then, when stationed in UAE, I got up put all my gear on and was walking out of the tent, then waking up and wondering what the hell I was doing. Stress was the main cause for all these examples, it doesn't happen anymore.
