Interestingly, I have the ability to increase my resting pulse rate and then decrease it back to normal, without using any specific imagination techniques. I believe this is closely linked to the release of epinephrine into the bloodstream. To achieve this, I simply recall the sensation that arises when my body has the actual epinephrine response. This either tricks my body into responding as if there were an actual epinephrine response, or perhaps a small amount of epinephrine is actually released - I'm not entirely sure. Apart from increased pulse, my pupils also dilate significantly for a short time, which is also can be linked to adrenaline response.

I've had the opportunity to test this in a clinical setting under an ECG. Not only did it increase my pulse, but it also caused the QRS complex to invert. Upon seeing this, the doctors advised me not to continue with this practice. However, I didn't experience any negative effects from this experiment. On the flip side, I haven't found any practical use for this ability either.

I would be intrigued to connect with someone else who has a similar capability. It seems that those internal "feelings" is as close to direct control as we can get.

As of pain, I have similar experience as well, except instead of detaching myself from the pain, I "look" as closely as I can. At a certain point pain decomposes to what it really is — electrical impulses, and from this point it literally starting to feel as electricity going through your body, quite the same feeling as if you accidentally grab both pins of the electrical plug, albeit not as intense.

well, you can reliably trick a polygraph

If we're discussing controlled changes in physical condition using various equipment that allows measurement, it's called biofeedback. If done without equipment, it includes various types of autogenic training.

Its as if feelings are the driver, and the physical reality follows.

I like to think of reality is a wide highway, and we have a lot of flexibility in the lane we pick in most cases, and other times we're funneled down to a single lane.

When systems are built on top of systems built on top of systems, cause and effect get lost in multiple levels of hysteresis.
