I think everyone experiences these types of feelings in particular places. I agree, 100%, with Axman that at least some of these feelings can be attributed to EMF. I think the rest are basic, human intuition. I know that some would like to term these feelings as “special,” but through my years of being active in the paranormal and talking with countless other people both inside and outside of the paranormal community, I have found these feelings in particular places or instances to be universal human experience. I honestly can not recall one person I talked with about these matters that did not have at least one very vivid memory of such an experience, usually more and often repeatedly reported in particular places known to them.
Most interesting to me is the fact that those outside of the paranormal community that I spoke with regarding such experiences considered these feelings normal, “everyday” types of experiences - they simply took them as they were and moved on. They felt no need to further investigate them or to put a label on them. The term “sensitive," “psychic,” "paranormal experience" or any other label was not in their chosen vocabulary or a term used to put a meaning to their experiences. What a breath of fresh air. I’d just be quiet and listen to their stories and be happily in awe at how similar we all are as human beings, at least in this regard (and, in the realm of many other types of apparently paranormal experiences).
I will grant that the feelings, for some, seemingly are more profound and/or incorporating other sensory experiences. Call that what you will. Some here know my over-all beliefs regarding such matters and my history of chronically having to deal with them. However, I think the basic cause and response of such experiences is purely, humanly universal - the meaning (or, lack thereof) formed from them simply being a product of the mind-set of each person who experiences them.
