So I’ve had this for years since I was a child and it sounds crazy but I want to know if it’s actually a thing? (It’s not really relevant but it’s really beginning to annoy me) 

It’s hard to describe so I’ll give examples, I was listening to a video and they brought up rocks - for some UNKNOWN reason, my brain said ‘what would it be like to chew on a rock?’ With an image of my teeth popping out and now I have physical tooth pain which is annoying to budge. 

If someone brings up a knife, I can feel it in my abdomen or rib and the pain again is hard to make go away. It’s not a bad pain but a dull pain so it’s really annoying… 

Has anyone experienced or heard of this before?
