Ever since I can remember, I've had been able to "sense" people coming near me before they were close. The feeling is like... my ears open up... I don't really know how else to describe it. I've never had the ability to control this feeling, and over the past few years it's been activating when I've been completely alone, which makes me think of spirits or some other sort of entity being around me. I just wonder if anyone knows what this feeling is, and if I can control it or not, or if it will just remain unknown and uncontrollable.
