Music in Dreams

I'm working on that song from my dream. I hope to have it perform-able by my gig next weekend!

I play the piano IRL but usually when I get a chance to play it in my dreams something happens... the dream ends or someone attacks me or goes playing the piano not letting me play it.
Once we had to play Chopin's grande polonaise brillante prima vista (at first sight). My friend tried to play the piece. He doesn't play any instrument and even if he did, he (or anyone else) would need at least about ten years practice to even consider trying to play it.
Another time there was a piano in middle of our class. This time we had to play something easier, für Elise (even I can play it). Again that same friend of mine went to the piano and started playing. He started it right but then he started playing it differently. The melody was something like that of für Elise. I went to him asking what he had on his score. He showed me it but I can't remember more of it.
Then I had two dreams where there was beautiful music playing. In both of them my friend (not the same as in the two other previous dreams) went and shut it.
I also think I have heard some music in a dream that doesn't exist in the waking world.

Well, I played Robot Unicorn... And some days later a non-lucid ended with THIS music http://www.youtube.com/watch?v=eSMeUPFjQHc

:panic:

Music in my LD's isn't a new thing for me. Ive enjoyed 43 operas & 32 symphonys, all orginial, created entirely by my mind, i never write them down, as its pretty hard to remeber such long peices, and the fact that i never intended for anyone but me to hear the pieces.
