>> Maybe as a side-effect of this processing, they also aid problem solving. This is an interesting side effect considering when I have a tough coding problem, it keeps my brain churning for hours and it keeps me from falling asleep. It's clear your subconscious comes to the forefront as your conscious part of your brain turns off during sleep. Having your subconscious solving complex problems is fascinating to me. I'm wondering how you could activate this on purpose, without having these issues keep you awake at night when you consciously can't let go of a problem. The implications of this are pretty cool if you could pull it off.
