The Lab Notebook

I'm in a big building of some kind. I'm high-school-aged, and I'm walking around in the building as part of a group of other high-schoolers [none of whom I recognize individually]. There's a tall table with a bunch of half-sheets of paper on it. They're sign-up sheets where we can sign up for the activities we want to do at an outdoor camp we're going to go to. I and several of my friends sign up for tennis. I think, Since when am I interested in tennis? [I'm not, in real life; I haven't even played it since high-school PE.] I also notice that one of the activities we can sign up for is beer pong. This strikes me as odd, too, since we're high-school students. Then I recall that in a previous dream in this setting [which, once again, I don't recall at all now that I'm awake], I learned that either the drinking age here in this setting is 18, or there isn't one at all, I'm not sure which.

Side notes:

I managed to have a lucid dream last night, despite having drunk wine several hours before going to bed. I think the fact that the last thing I did before bed was writing and posting a dream journal entry helped a lot. In this dream, I was aware that I was dreaming, but the thought of going off and doing my own thing, rather than going along with the dream plot, didn't even cross my mind. I don't know why not. I also don't remember why or how I became lucid.
