I have often wondered what causes sleep walking. While I was growing up I used to talk in my sleep a lot and it kept on growing worse to the point where I did weird things in my sleep with only faint memories of doing them the next morning after seeing misplaced items in my room or wearing something in an odd way.
The night I remember the clearest was when I woke up shivering on the top of our kitchen roof. I have never enjoyed heights and crept my way cautiously back to my open bedroom window and hopped back inside. From that point on I always made sure my windows were latched before going to bed in hopes that I wouldn't do a repeat and maybe even fall off the roof.
Talking and walking in my sleep have both disappeared since we got married which makes me very happy. It is rather unsettling to be doing things without being aware of doing them.
Have you ever walked in your sleep? And no, staggering into the kitchen for a cup of coffee in the morning does not count as sleep walking.
