Sense of proximity

I have another theory that says we can look even farther than the periphery ..and tell when someone is approaching ..or even thinking about us ..at a distance well beyond the means of ordinary senses. I call it a sense of proximity. In prehistoric times, it was part of a perceptual system that picked up early warning signals ..but atrophied with disuse. Who knows, there might still be remnants of it laying dormant in some people.
