DAE – Rub nail with sharp corners to relax

r/

Does any one else feel impulses to take sharp corners and rub it between the side of your nail ? In between the nail and skin??

I love using my bedsheet or pillowcase when I’m laying down and making a sharp corner with it and rubbing it on my fingers. It relaxes me so much.

This is so weird. Even describing this is making me feel the sensation as I’m typing.
I’ll even take pieces of paper and do this.

What is this???

My husband thinks this is so weird and l’ve never met anyone else who does this. But there HAS to be someone.
