I tend to have two kinds of musical dreams: there are those when my fingers are magic and everything comes out amazing and those when everything comes out awful. I think I've managed to retain a dream melody once or twice. Recently I dreamt a poem that was absolutely amazing but when I woke up it had melted away even before I awoke. I have some dribs and drabs of it that I'm trying to reassemble into something coherent.
