Last night I had a dream that I was in my psychology class at school, (with the real teacher, room, students and everything.) and the teacher was discussing lucid dreaming. She said lucid dreaming several times and in my dream I said "Hey! I know what that is! I think I'm having one right now!" And I counted my fingers, all 12 of them but I didn't become lucid. The teachers discussion went on and I eventually just woke up. What happened? I've gone lucid before from a reality check, but this time it just didn't work :/
