I happen to sometimes sleepwalk. Sometimes I just walk around a little bit, sometimes I'll pour myself a glass of water and not drink it, but other times I'll go outside (in fact I've driven while sleepwalking before).
I wondered, what if one night I decide to sleep in a baby doll and I get up and one of my roommates happens to see me (they don't know I dress)? What if I head outside?
Once I discovered I had gone outside (in male mode) and since I sleep barefoot during the summer I checked the bottoms of my feet. They were clean, so I wondered if I put flip flops on to go outside (tasks are performed half-baked while sleepwalking), and also wondered if I even put clothes on because I usually only sleep in underwear.
I've known for a few years now that I sleepwalk, but since recently I'm dressing more and more I think I'll be outing myself to my roommates and/or neighbors in my sleep.
