My little sister used to frequently attempt to pull secure objects apart when she woke up. She once tried to pull the ring off of my other sister's pacifier and the screw-guards off of my old futon because they looked like m&ms. She has also woken up and, after a few seconds of stretching or yawning, screamed seemingly random things like, "Well if I knew it was yours, I wouldn't have broke it!" or "Why don't you go sit somewhere else?!"

One of my friends used to enjoy talking about sandwiches while he was sleeping. He also used to threaten to put ketchup on my sandwich just because he "felt like it," knowing that I don't like ketchup.

In Psychology, we learned about this guy who murdered his ex, who lived something like forty miles away, with an improvised weapon after he drove there from his house in the middle of the night. In court, his defense was that he was sleep walking and he was released on time served.

Other than waking up in odd positions, I've never sleep walked.
