I did have a sleep study done, found that I do not have apnea, but I think I might have Narcolepsy. I fall asleep at odd times during the day, maybe just for a few minutes at a time. I think I do dream then, too. I haven't been tested for Narcolepsy yet, though. My doc was more concerned with apnea.

I do sleep alot during the day, sometimes for a couple of hours at a time. Even after I sleep at night, I'll wake up for a few minutes, go potty, smoke, and then go back to sleep. This pattern repeats itself many times throughout the day until I HAVE to get up (ususally in the afternoon).
