Bright lights. Not only painful on the peepers, but disorienting. The total loss of vision that it causes freaks me out.

Wide open spaces. Really. Like in a wide open field with no trees, no walls, no nothing. I get panicky and get this odd urge to find cover and quick. Almost like something will swoop out of the sky and get me. One time, while out in the road, I stopped in the middle of the some wheat field infested part of the US. Big mistake. Just stopped to, you know, take a little pit stop at the side of the road. Panic set in, followed by a bad panic attack. Hyperventilation. It was all I could do to get back on the bike and get the heck out of there.

It should be noted that I only feel this sensation when on land. Out at sea, I can stand on a boat, see the horizon in all directions, and be just fine.

No clue at all why that is.
