Dreams.

I had a rather interesting dream today, but for some reason, I couldn't remember much of it. (
I only remember being at some kind of station, either underground or maybe even a space station. I'm not sure, but there was this device for drilling into the ground (like in cartoons, and I think the subway also uses something similar), and it needed to be tested.
Maybe I was supposed to be part of a team, or maybe I was just hanging around there for some reason. And then, it seems like there was an accident... that's all I remember.
