Tweetindeed I have . you wake up in the middle of the night and think WTF... what the hell is wrong in my head. I got issues... lol
I don't know I actually did a search on it before and the most logical answer to me was your brain takes the past memories the images stored and tv and radio you have resently viewed mix them up and add the emotion and feelings you went to bed with and you get one screwed up view of past, present and current thoughts..in a version you wouldn't even think to recreate.. the mind is a crazy place for sure.
