Hey I hate most blood and gore horror movies, but remember they are only make believe and just don't watch them. Watch chick flicks, or Happy Feet.
Sleepwalking, which also is called somnambulism, is more prevalent in children. If you have never had this problem you are most likely pretty safe.
Let go of the "stinkin thinkin" and stay in the moment. You will be fine, just stay in the present and do not worry about the what ifs>
