DH,

Yes, I used the technique during college Calculus when I didn't know how to solve a problem, which was almost always. I would slip into the dream state with the problem in mind and a solution would be shown. I would write it down and turn it in, not really understanding what I was writing. The professor said that my solutions were correct, but that I was using methods that he hadn't taught yet. I don't recommend this approach because even though I passed the course, I never had any idea what was going on and still know nothing about Calculus.
