conscious and subconscious minds disagree

I'm a musician. I do my own music arrangements I completed my latest arrangement and had a dream about it the night after. In my dream the ending verse was re-arranged. I could clearly hear it. Much better I thought. When I got up I went to the computer and fixed the song. My subconscious has better music understanding. Sometimes I dream of original songs, the melody, the lyrics, everything. When I wake up it vanishes. I hate when that happens. My subconscious is a prankster.
