Musical Dreams

I dont know if this happens to everyone, but every few weeks or so I dream music. When it happens it's the best dream you can have, but I hate the fact that as soon as you begin to wake up it slips away, and by the time you drag yourself out of bed, it's completely gone - can't even remember a note. This is one of those days and it's also when I rue not being able to play an instrument, because even if I do remember something, I've no way of repeating that experience of the dream. Frustrating, but that's life I suppose.
