Weird stim?

Setup to my point: So ive been watching walking dead, got to a point where Glen made a shiv out of a arm bone. I imagined the process of that happening to me. Then shook out the feeling in my hands. The point: do you ever get like an ick feeling that doesn't go away until you shake your hands or something? Cause my ick is usually in my hands and I gotta shake the feeling away
