DAE ever have a feeling that their hands are on backwards?

I'm not high or drunk, this happens fairly often to me, and I'd like to know if it's a shared phenomenon, or if I should just add it to the list of odd things about me.

It's a feeling like my hands could bend backwards, like hands normally do, just the other direction. It sometimes gets so certain of a feeling that when i curl my hand into a fist proper, it makes my brain freak because it's receiving 'your hand is bending the wrong way' messages, when the hand is, in fact, moving the way it ought to.
