A dream within a dream: I'm telling a group of people about a very funny dream I had. Everyone's laughing, including me. There were a lot of absurd details, but the only one I can recall now is that, because of some misunderstanding, in the dream-dream I sprayed an adhesive on the piano keyboard and then sprinkled it with some abrasive powder (like sand).

The SO woke me because I was talking and laughing in my sleep. He thought I was having a nightmare.
