I dated a girl in college who was staying with me at my parents. I knew she sleep walked some times, but nothing crazy had ever happened. Anyway, one night she sleep walks buck ass nude right into bed with my parents. Needless to say, she was mortified, thankfully my parents were good sports and laughed it off, and by the end of the next day everyone including her was able to laugh about it, also she slept clothed for the rest of that trip.
