I dont really ever sleepwalk. However, there was one time a couple of years ago. We put our two cats to bed in the laundry room one night. I woke up at 11pm and saw one cat on by bed, meowing. I scooped her up in my arms, walked over to my dads office where he was working and said "Look dad, Ziggy (that was the name of the cat) has got out of the room!" He looked confused and said "There's nothing in your arms." I looked down and there wasn't. Now that was CREEPY! I could've sworn I was awake the whole time!
