What do you think of this theory?

I've had SEVERAL wet dreams like this. I think because my very first wet dream was like this might have affected the ones after it. My own theory was that at that time I had not yet experienced an orgasm or had I ejaculated, so within the dream my mind sought out the experience that made the most sense involving those parts and needing to release. It was a very beautiful dream with nothing more than hugging a girl as far as action goes, and then melding into one being and feeling water flowing all over me and then becoming water. Sounds crazy. And naturally this ended with a strong urge to pee but it was withheld and kept building in tension. After a sudden increase in heartbeat I felt myself finally going for what seemed like a minute, and I swore I was actually peeing but not freaked out by it - even felt like a warm wetness was spreading. When I thought it was done it seemed to strangely start up again. I think it did this a few times before I finally woke up terrified that I had actually wet the bed, but it was in fact my first wet dream. I've also heard that having a full bladder can help trigger this type of dream since it puts pressure on the prostate or something like that.

Well sounds good, but you need evidence to prove it in order to tell if it's true or not. What things have you got to back it up? Also, maybe it's worth using proper terminology i.e. not words like 'piss'
