Very very cool to have retained the memory.

When i used to play the piano i would spend pretty much all day playing. I would literally play until i would start falling asleep. I would then give in and go from the piano, right into bed, and i would have the most amazing and original songs play in my mind right as i started falling asleep. As soon as i would wake up the memory would fade, it was very frustrating because it left me with one of those feelings where you have the memory of something on the tip of your tongue, but it didn't come back.
