After spilling a bit of coffee just now, I was reminded how much I hate touching paper towels. I know it might sound strange, but feeling the particular grainy texture of paper towels against my hands is particularly unpleasant for me and sometimes makes me want to shudder as if nails are being dragged across a chalkboard. Well, perhaps I am exaggerating the intensity, but you get my point. I sometimes get a similar kind of bothered feeling when I hear certain markers writing on paper-- almost as if I can literally feel the texture of the marker on the paper, and again a sort of nail on chalkboard kind of unpleasantness. On one occassion I had to ask my brother to use a pencil instead of a marker because I couldn't bear it. I use the example of nails on a chalkboard because it is the closest thing I can think of that is more or less expressed universally. Although it seems more natural for a high frequency sound to be bothersome than the feeling of a paper towel, it seems to me that there is something beyond just high frequency noise that makes the chalkboard thing particularly unpleasant. Does anyone else have these sort of idiosyncratic sensory bothers? I'm just curious-- it would be interesting to see how often they crop up and what forms they can take.
