there are many theory's on this. i think that what you body feels and your brain thinks, comes into your dream. and you NEVER dream about something you have never heard about, thought about, saw, felth, smelled... etc etc for exemple lots of kids wet they're beds because they dream that they are on the toilet. and sleepwalking is mostly something people do out of addiction, like gaming and stuff when i was 4 years old, i walked down 2 stairs (while asleep) put on the tv, and the nintendo (the oldest one ever :P ) put in supermario 1 two or three i dont remember... took the control, sat down and fell asleep... when i was 6 i walked down 2 stairs again, went to the basement, found a load of chocolate bars, ate em all and went back to bed ( all while asleep) i didnt remember, but my mother definateley knew it, my whole face was covered in chocolate and all the bars were gone :lol: hope you enjoyed, killerken 8)
