I was part of some puzzle/academic competition thing. I only remember two parts. In the first one I had to write an essay about something, so I snuck into a library that I wasn't supposed to know about and convinced the librarian I was there for some other reason. I think my opponent might have had a similar idea. I think the essay had something to do with some famous boxer. In the other part, my team and I had to raise the water level in a small underground lake. We'd found a super long garden hose, and were pouring water in from bottles while trying not to fall down the cliff leading to the lake, when I recalled a puzzle that we had previously solved. So we trekked back to the surface, hose in hand, and found a drnking fountain that we'd rigged up earlier to do something. After some discussion about how water responds to gravity and wondering who would be paying for the water since the event was being held in a public park, we plugged the end of the hose into the spigot of the fountain and then sent someone to check the lake while trying to prevent other people from finding out what we did the water fountain. We must have succeeded since a nearby dumbwaiter started producing fried fish for us. The dream ended before I got any, though. Anyway, surprisingly coherent for one of my dreams.
