Some years ago, I had a vivid two-punch dream, in which I felt I was being recruited into a Russian intelligence agency. I was lucid—that is, aware I was in a dream—from the beginning. Standing in a hallway with a crowd of other people like me, waiting for whatever was supposed to come next, I was practicing my lucidity skills by trying to levitate, and being reasonably successful at it. People were chatting among themselves, but I was minding my own.
