I've sleepwalked once in my life that I remember. Wasn't a big deal, I was young, ended up in my brothers room or something. I've also had these weird experiences where I partially wake up when someone asks me a question in a deep sleep. I answer them with somthing that makes absolutely no sense, and I am aware of what I'm saying and doing I just can't do anything about it. It's REALLY weird, pretty funny too. I'm sure Leslie has some good stories about that. Finally, I move alot while sleeping and apparently carry out entire conversations that you can follow one side of while I'm zonked out. I also laugh a lot while I sleep.
In any case, I have never, ever done anything like this.
