I agree with LN(BB). You might have actually worked out a few things in that dream. Or it may be pointing you towards something.

There used to be a song which it seemed nearly everyone would request when I performed. The problem was that I was unable to work out the chords and so had to decline. Then one night, I dreamed I was at a party and the same old request came up. But this time (in the dream) I decided to give it a try. The song went perfectly and the chords were just right.

I woke up that morning and immediately grabbed the guitar and tried the chords I had used in my dream. They were perfect!
