I dreampt that my parents and I had drilled a cyllindical hollow out out the tree in our front yard (which was much taller than in real life). In the hollow, which went all the way from thr ground up to the top of the tree (way up) we poured concrete, and then Mom coated it (the cylinder of concrete in the tree) with aluminum so it could slide easily. And the cylinder of concrete had a hollow spot, so the whole thing was like an elevator. Like an elevator from ZDoom, really, where you don't have to worry about stuff like 'what makes the concrete go up and down'. I was rather worried about the health and structural integrity of the tree, but it seemed to be holding up OK.
There was another dream where I was was running around in a game that was Tribes-ish but much cooler than Tribes and not crappy and stupid like Tribes. I was telling someone who was running around in it with me how old games like this that used software renderind were usually cooler than new games. This game had some big visual glitches, though. Like mountains dissappearing when you were within a certain distance and re-appearing when you got farther away.
I think I'll write that recital report for my dumb music class now.
