I worked from 8:30 to 4:30 yesterday, and spent most of the late afternoon and early evening recovering. After visiting Trader Joe's and picking up some chocolate, I was almost ready to crash, but stayed up a little too late on IM.
While asleep, I dreamed that this apartment complex's pool area had turned into a large computer-driven simulation of the Earth, much like Biosphere II. I ran a projection on it based on current trends, and it hit an ice age. I was freaking out, but then there were two people there more senior than me (project manager/teacher types) who grabbed hold of me and calmed me down, and then I went into the simulation, inadvertently passed gas, and then realized that I hadn't included carbon dioxide in my simulation! I (well, actually, I think it was Naomi, but it was I-in-the-dream) got all hyper and stuff, and when I ran the simulation again, modeling Death Valley, it was at 1,000,000-something degrees.
