I think I have an evil genius sitting over me, sending me all my perceptions. I was just about to hit "stop" on my CD player, I had my finger hanging over the button, not yet pressing it, just hanging there--and it stopped. I never pressed it. It's as if those computer systems in the CIA experiments on their vat brains where I sit floating in a jarful of fluid as those mad scientists send me perceptions of the world--it's as if their computers saw me moving to press the button, there was a software bug, and the music stopped out of sync with the rest of my perceptions. Some scientist somewhere in a white lab coat is giving admonitions to a pimply-faced teenager who's eating cheeseburgers and watching the network, the scientist saying, "We must never let our vat brains learn that they are vat brains--don't let it happen again."
