I can only speak for me. I use to be very artistic and actually work as artist for short time. I am still very creative, but in different ways. I see things most do not. I can come up with things out of the air. It makes me who I am. As for the racing mind. I go to sleep and the brain does not seem to stop. I am up and can recall what my brain was thinking the entire time I was trying to sleep. Don't remember what it was like to not have numerous thoughts or something going on in my head.
