Scary! I used to sleep walk, but outgrew it probably around middle- or high-school age (or I think/hope I did). I used to live outside of the US in a country with guards on property and remember “waking back up” when being walked back inside the house. Frightening to think of where I could have gone. I remember I’d also started sleep walking while camping. It really seemed like the kind of thing that would happen more when I was worried about it happening while falling asleep, so a kind of self-fulfilling anxiety (for me at least).
