I've a terrible sleeping pattern and unless I've something to do when I first wake up, I usually go straight back to sleep. I've been this way for atleast 4 years now; going to sleep at 4am and waking up at 3pm. I have "half"-dreams everyday, it's not a healthy habbit. The dreams nearly always relate to whats on my mind before I fall asleep I have no control over the dream (I just dreampt I died, resulting in me finding this thread). I just thought it sounded similar to what you have, and that maybe you could reflect off of this.
