Early morning inspiration

You hear all the time that many people get their best ideas in the shower or in some very specific places and circumstances. For me, it's always the same; if something preoccupies me a great deal, I'll wake up in the wee hours of the morning, often with a solution or most of the time, on the verge of solving that current problem of mine. That's my best thinking moment and it certainly is my most creative environment. I guess that I go to sleep with a puzzle to solve, my subconscious mind gets to work and when it's about ready, it wakes me up with some answers or at least a few useful threads to follow... What about you?
