I'm surprised that this one isn't on the list that I've seen, because I know so many people who actually do this also.

I constantly write out words that I see in the air. So when I'm watching TV, I constantly trace out the brand name of my television and the logos of the stations. I have major issues when I watch CNN because it has this think that traces the logo that I have to pay extra attention to and follow. If this seems weird, but friend will sit type out words that sees.

Also, all the doors in my room need to be closed when I sleep, and I need to have at least a sheet covering me, even when its really hot out. I think this is left over from the child-like logic that monsters lack the ability to open doors and touch bed covers.

Also,particularly at metro and train stations, I need to walk on each one of the "special" tiles designated to keeping you from falling off the platform. But just in general unless they're really small or large I need to walk on one of each tile.

That's all that I can think of right now.
