Well, this morning was bizarre.
The actual content was nondescript, just playing Left 4 Dead where there were a dozen hunters and they had guns. The interesting part was that I was really close to consciousness. I could with concentration lift my arm or leg (in real life) and feel it move, while still in the dream. Also I could will myself to wake up, actually open my eyes and look around, then go back to sleep seconds later and dream again. Only the content was different when I went back in, like it had reset. At one point I was in a house with pink wallpaper and purple furniture, still shooting hunters.
Too weird.
