The 10% of your brain thing is a myth...

The conscious and subconscious parts of our minds are permanently intertwined, IMO...for example, I cannot consciously control every detail of my dream even when I am lucid--I must rely on my subconscious mind to take care of the details and keep the environment relatively stable while I focus my attention on the few things I want to alter. Pesonally I don't see it as one or the other having control or needing to separate from the other or having dominance over the other--I see them as an interconnected web, each relying heavily on the other to function as a whole.
