Funny you should bring this up, I was just thinking about my dreams. When I was getting sick while undiagnosed I had no dreams for about 1-2 years (I know I must have had them but didn't remember any).
Now I sometimes get them. The last one I had was creepy:
I was walking around an airport with big windows and bright sunlight and looking for my way through when someone led me to a huge cement door like 12-15 ft tall. I walked in, and the door shut and clicked behind me and I found myself in a hallway, with tall concrete walls and walked for a while as the hallway made several right angle turns, then it dead ended. I freaked out and knew that there was no way out of the door from inside. Walking back to the end of the hallway where it dead-ended was a tiny window, like 8 inches square with thick glass. Outside was bright sunlight and there was sand covering 3/4 of the window. I sat down and there was a manuscript of some kind on a ledge in the wall that said "My last great love 7-24..." I did not pick it up as I knew I would be stuck in there for the rest of my life. I looked at the small window realizing it was too small to fit through, and considered kicking it out to try and scream, but was worried about the sand coming in. Then I woke up.
I never used to get such devious mind-**** dreams before UC - although I admit they always seem original and creative in their own creepy way. Seems like a strange, alien intelligence at times - like my colon too - never ceases to fascinate me how dreams can pull all of this up and completely surprise yourself, like we have a hidden author in our brains pulling the nightshift...haha
