I used to work in a machine shop in Florida that had no air conditioning. Summer time was always barely bearable. A woman who worked there would sometimes complain about the heat, sweat beading on her forehead. I'd think of a certain piece of music (this was ~25 years ago, so I don't recall what music now) and goosebumps would pop up on my arms. I'd tell her I really didn't see how she could be hot, because... "Look, I'm actually a bit chilly." Even though it quite amused me, she never seemed to be amused, though at some level, maybe she was. She kept coming back to complain after all even when she knew what my response would be.

I can, for the most part, now produce goose bumps without thinking of any music. I just feel the feeling that produces them (lovejoycompassion*awe), and they pop up, often accompanied by a lump in the throat and/or catch in the breath.

The subconscious has little ability to distinguish between imagination and reality, in the sense of, e.g. one who has a fear of flying will display the same physiological manifestations whether he's boarding a plane, or just imagining boarding a plane. The subconscious reacts the same to the perception regardless of whether that perception is through the mind's eye or the physical eye. This is how NLP works. By inducing the reaction in a safe space, it can be minimized or eliminated. Once minimized/eliminated in the office (or wherever), it remains minimized in the triggering circumstance.
