I've had times when during a dream, I've heard a melody, and when I woke up, I picked up an instrument and was able to replicate the melody I heard when dreaming. If I can come up with good sounding melodies in my sleep despite being a fairly unpracticed musician, I can only imagine what geniuses in their respective fields are able to figure out unconsciously! Obviously the presentation within the above described dream is fairly dramatic, but that might just have been his mind's way of making sure he remembered it when he woke up.
