I used to sleep walk frequently as a child. One night I remember my dad waking me up. I had opened my bedroom window and had my leg up trying to climb out of it! Good job it was a high, small window otherwise I would have been splattered on the pavement!
Another favourite sleep walking story that my parents told me about happened when I was a teenager. I stormed into their bedroom in the middle of the night totally naked, and told them to f*** off! Hmmm, don't think that needs much interpretation!
