does anyone else get distracted imagining people's bones while they talk to you

looking at people's faces, i increasingly find myself imagining what their skulls look like, especially when they open their mouths and i can see their teeth. or when they move, i imagine their fleshless skeleton repeating their action. everyone is just so skeletal when you look at them for too long.

i don't imagine it in some creepy way, it comes into my head unwillingly and actually upsets me. it happens a little less with fat people because their facial structure is less defined.
