While having only "mild" success at lucid dreaming, I think I have fairly good internal awarenesss that I would like to channel toward lucid dreaming more effectively.

So, does anyone know what part of the brain is aware of the context of the situation, ie) what part of the brain becomes activated during lucid dreaming that previously was not. I meditate and am an amatuer artist and feel I can switch between the left and right brain pretty effectively. And lately when I concentrate, I can feel the front of my brain tighten up.

My guess is is that the upper left frontal lobe would be the portion responsible. Any ideas?
