Ah, hallucinating. I've really only done it once before I was hospitalized mid-August. I'm sure it's different for everyone, but for me, it started with a deep and inescapable feeling that something just isn't right (which is what I'm feeling now). Then, while I was at church, the colors of people's clothing were distractingly bright. The patterns in the carpet and in the wallpaper seemed to wiggle a bit. Every now and then, I would see a dark figure in the corner of my eye, but when I turned (or jumped) to look, there was no one or nothing there. The scariest part was when people's faces looked grotesquely distorted to me - eyes too big or too small, mouth too big, teeth all over the place... just freaky. Should be no surprise that I had a massive panic attack. That's how I hallucinate. Fortunately, 1.5mg of klonopin made it go away that time, and I have a feeling that the klonopin I'm taking now is helping to stave it off this time around...
