I used to ALL the time up till I turned about 15. The funniest one was probably when I was trying to climb up the wall. My dad came in and said "CHarles, what are you doing?" I said "trying to get to the next level." LOL, I had just been going through an intensive game of Mario Brothers 1 on the Nintendo right before bed.
Now I only do it sometimes when I am in a different place besides my bed. Like when I sleep over at someones house or camping, I occasionally sleep walk or talk in my sleep. But it isn't like before, where I would do it about once a week.
