When I was growing up, I had a habit of talking in my sleep whenever I was camping. At camp I freaked out my tent mates by crying, "he's coming!" Another time I was sleeping in a log cabin with my girl scout troop and started screaming loud enough that it woke up people sleeping in the other cabins. Another time I was camping with a group of friends for a birthday party, I got up in the middle of the night and tried to get into a backpack, but started getting upset that I couldn't get it open. Turns out it was already open and the backpack wasn't even mine.
