I don't have claustrophobia. Like at all. But exactly once in my life, I got in this weird state of mind where I got claustrophobic about my skin. Like oh my god I can't get out of it anywhere to really feel some cool air. Even sticking my tongue out of my mouth - that's still just a type of skin. Anyway after a while I remembered my teeth aren't covered in skin and started baring my teeth and breathing to get cool air on them and felt better.

I am fully aware of how absolutely psychotic this sounds and yes I'm usually normal. Also teeth are dentin.
