I dreamed of music and it's gone

Today I woke up with a beautiful origional melody in my head.

Now I can't remember it.

A few weeks ago I had the gituar theme from Brokeback Mountian in my dream and had a gorgeous melody and beautiful sad lyrics in a dream. I even thought for a while that I had heard it, that someone had recorded it and that it found it's way into my dream that way, but it hadn't.

I can't remember it anymore either.

Sigh.
