I have experienced something in a similar vein. When I studied massage, we were asked by one of our teachers to consider our ability to feel what is going on in a body by simply holding hands over or on the body. We all ran hands hovering over a person's body and would stop where we felt something. Interestingly 9/10 times the person we were reading confirmed that the area we stopped was an area of injury or pain... It really opened our eyes to using all of our skills to assess people we treated.

It is something that I believe we all have, we just need to tune in to it a bit more.
