Argh (dream)

I dreamed this morning that I had written a song. A friend was pestering me to sing it for everyone, but I was resisting because I'm a lousy singer. The earlier parts of the dream had had a nostalgia theme (digging through a bin of cartridges for extinct gaming consoles and cards for extinct CCGs). Going along with this, we were in my elementary school's art classroom, complete with blackboard and chalk. My friend started writing the song on the blackboard, one phrase at a time, and I was correcting the few words she remembered wrong. Then I woke up, and as soon as I was awake I couldn't remember the melody or any of the lyrics or even what the song was about. x_x So now I have no idea whether it was any good, or even whether my subconscious had stolen the melody of an existing song or come up with a new one. Argh.
