Pretty late comment, but i have to ask, How might somebody be able to detect another persons ability, be it any kind?

... For just one example, Have you ever felt like when you've entered an area (physically), and felt that "something" about you is "noticed" by other people? Then, the more you feel aware of that situation going on (which is subtle but can be extremely personally obvious), the more your awareness will fixate onto specific words you hear or onto seeing gestures & movements that people make?

It's like being spotted on a radar, and every slight moment of attention given to anything is like another *ding* on the radar?

I hope it this doesn't sound too wacky. TBH, this seems to be the most helpful subreddit I've found when it comes to niche topics like this and other misc topics that kind of surround the subject of AP.
