I believe that it is a combination of factors. Many of them relate to body language and movement. In my experience, a great deal can be told about a person, their relative will, and their mindset by watching their posture, gait, stance, etc. There are a number of online resources that can teach more about this skill if you are of a mind to develop or further it.
As for the non-physical factor, I can't explain how I sense it, but I just get feelings not unlike a change in air pressure, or a low frequency sound wave. It gives my skin a tingle. |
