One of the things I always heard (but never experienced) was that creative types used pot to enhance creativity. I never considered myself a creative type, so I generally ignored that aspect. Sure, I could free associate better to help with a problem, but that was different.
Then about a year ago I smoked what I considered "too much". I had to lie down to just get past it. As I was lying there, I closed my eyes. And saw the most amazing "closed eye visuals" that I'd ever experienced, accompanied by incredible music. The visuals were full color very detailed movie like, the music was orchestral and complex. It was totally new, nothing I'd seen or heard before. Then I understood what they meant. If I was a musician or a movie director I'd be transcribing as fast as I could.
