We Solve Problems in Our Sleep
Jeff Taylor woke in the middle of the night from a dream in which he created an electronic bulletin board that was lit up with eager job-hunters logging in from all over the map. He scrawled the phrase "Monster board" on a pad in the dark, then rushed to an all-night coffee shop and roughed out the plan for what became the stunningly successful internet job agency, Monster.com.
If you want to solve a problem, or need a fresh perspective, sleep on it. Write down your intention ("I would like guidance on X") before turning in, and be ready to record something whenever you wake up. Even if you have forgotten your dreams, you may find you have your solution.
