Has there been any research that found a link between dissociative disorders and dissociative dreaming?

I often have dreams where I view a very complicated story, with lots of plot twists, antagonists, protagonists, motives, causes and effects. However, while participating in this dream, I have no idea why people do what they do. At the end of the dream, when all is revealed, I smack myself on the knee and say, "Ah, Professor Plum did it in the kitchen with the candle. That's so obvious, why didn't I see that coming?"

Of course, I wake up and ask myself, "Hey, wait a minute. That dream came form my own head. How did I make up a story I couldn't figure out?"

I can't help but think that there are two folks in my head, one making up stories for the other to watch.

I have had no bouts with multiple personality disorder, as far as I know. I haven't lost any time, to my recollection. I still wonder, though, if dissociative dreams precede other dissociative disorders.
