We were arranging who was going to take what rooms, sets of two connected, people were sneaking about, discussing the matter.
I was following around some olderish guy, various other people were milling around, we climbed up a stack of books/a ladder to an observation room, people wer floating around outside it.
Arf, when I woke up one of the things I remembered was only that I noticed, crystal-clear, that I was in a dream. No other details. I was waking and then falling back asleep, so that might have had some effect. All my lucid dreams seem to have occurred early in the night, and I don't remember them well...
