"The subconscious mind is a powerful problem solver. I believe this is why it is common to wake up in the morning with an unsolved problem, worked out."

Have you read anything about this? I do this all the time with my course work and I thought I was just strange. I can't tell you how many times I have banged my head against the wall with an assignment until I went to bed and then proceeded to get up an hour before it was due and finish it with no problem.
