Have you ever had an experience that completely shattered everything you thought you knew about reality -- even if only for a second or two?
Off the top of my head I can only think of once that it happened to me, and once that I made it happen for someone else. A few years back, I was at work, and a co-worker said "Hey, you wanna see me levitate?" Of course I want to see you levitate. So he walked away about 10 feet, facing away from me, and shakily levitated a few inches off the ground. For a split second, my brain was exploding -- everything I thought I knew was wrong. Then I came to my senses and realized it had to be a trick, no matter how convincing the illusion. Then he showed me how to do it. A few months later, I showed some of the other guys I work with, and unbeknownst to me, one of the cleaning guys saw it. He later asked one of my co-workers if I was a witch or something. I guess that maybe also counts as breaking someone's brain, but that's not the second story.
Okay, the other time, a friend of mine had come back from few months in Europe, and I was helping him edit his photos. There was one photo of some fancy building, and some random person was standing in the shot. He mentioned that he wished that person wasn't there, and I said "You want me to take him out?" If you've ever used the clone tool in PHotoshop, you know how this is done. However, it was a fairly complex background -- the guy was standing in front of something I'd describe as ramparts. I clicked to select my clone location, and when I went to paint the guy out, it just so happened that the clone location I had selected was absolutely perfect, so that when I made that first stroke, it really looked like I was literally just erasing the guy out of the picture, revealing what was behind him. My friend's jaw literally dropped, and he said "what" with a really small, shaky voice. Then he got it, and I laughed, and he acknowledged that his faith in his perception of reality had been shaken to its core for just a moment.
These moments are all too rare, but also incredibly awesome. Do you have any?
