What I'm saying is it's often times your "perception" of reality which is influenced by what's in your head (mood, etc.). Not necesarlily what's really going on (in reality).
I think the classic example is when Jerry was so upset with Phil's playing that he threw him down some stairs after the gig. Jerry was nutty at that time. He thought the music sounded like crap and was a struggle, etc. But when he listened to the tapes later, they sounded amazing. What changed?
