when a fly or bee or mosquito buzzes near my ear, i get a strange, involuntary muscle spasm in the sides of my lower back. it's very annoying and ticklish, semi-paralysing, almost to the point of being painful. i have asked countless other people if they get this, they all say they don't. i have looked up info on this online, and find no references to it.
do any of you get this? obviously it's neurological, and i wonder if there's an ASD tie-in?
i have a weird theory it might be some vestigial, leftover reflex from when we were animals, like when animals use their tails to swat flies, or, as a friend said, when horses "do that weird skin-twitching thing".
