Why does it always hurt a lot when the doctor says "well, this is gonna hurt a bit"?
Let me try to offer an alternate physical explanation.
My guess is that using our thoughts in meditative or visualization techniques, we are able to have physical effects in our bodies--just like we do when we decide to walk or perform some other physical activity. Now the thing is that these activities are unnatural or unusual to the functioning of the body. So they create disturbances similar to panic or anxiety attacks, to put it in psychological terms. These attacks may result in all sorts of hallucinations or delusions or visions.
If you want to feel heat in your legs, stay out in the freezing cold without shoes for a long time. First you feel cold—and no, this is not a suggestion. If this does not help, your nervous system adapts signaling you that it is hot. Eventually, you stop feeling your feet and frost byte settles in certain areas. So this may all be part of a survival mechanism controlled by the nervous system.
It is similar with hunger. After a couple of days without eating, the hunger goes away and you can last 60 days. Later on, the nervous system may again send signals, such as muscle spasms or twitching, and eventually hallucinations, sometimes of food like in the cartoons where you may see a person with a body of a roasted chicken (or a mirage in the case of water deprivation in desert situations). For some individuals involved in religious worship, they may even have mystical experiences. But this is again the nervous system telling them “You’re gonna die motherâ€.
Yet another example is sleep. If you stay horizonal for a long time like I've done watching TV, you may experience a distancing from the set and a trance-like sensation. Does this mean you are having an out-of-body experience? What may be happening is that the fact that you are in a sleeping position may be sending a signal to sleep. However, your desire to continue watching the set has the nervous system confused. So to satisfy both, it adapts by keeping you in a sleep-awake state, similar to those cases where you dream and in your dream you dream that you wake up but you're still dreaming. Waking up to a dream is possible because the dream may be so good that you really don't want to wake up; but it may be time to wake up because you may have had enough sleep or the alarm is about to ring. So the nervous system adapts by giving you both.
The ability of the body to radiate heat should not be so mysterious. Simply think of a fever. Isn’t that also a survival mechanism meant to fight threats to the body? We don’t find that to be so impressive!
One final note. Many of the sensations we experience may also be conditioned since birth. Meaning that we’ve basically learned what hot, cold, hunger, thirst is. Of course, there are physical requirements of the body. But the sensations themselves may be experiences we’ve learned in time. They’ve become wired into our neurons and this may be how in times of danger, the nervous system will attempt many possibilities to keep us safe.
