I think we as human beings cannot help but project our own custom fit life "shoes" onto any situation we wind up in. "Try walking in my shoes". We all have our own set of truths based on how we grew up and our own special set of emotional cocktails, personalities, etc. One person's interpretation of a creepy vibe could be, to someone else, a mixture of cooling temperatures, a bad mix of electromagnetic overload, and a subconscious ghost story from a camping trip when they were 9.
Here's a moment from my childhood where I experienced an overwhelming sense of "creepy" when I was a kid. I was probably about 8 or 9 years old, visiting my grandparents in Kansas. They had this "radio Teddybear" toy. He was about a foot or so long, tan, cuddly soft and had a radio player in his back. One day I was sitting at the top of the staircase that lead to the basement and for some reason, there was just the right mixture of elements going on that etched a memory in my mind, and caused the most unusual sense of "freaky" within me. A new song got served up on the radio (can't remember what but I'm thinking it was some 80s contemporary tune), I was holding the bear nearby, when I looked down at the bottom of the stairs. There was this vacuum cleaner, one of those skinny long hosed neck kinds, sitting in the middle of the walkway, next to a furnace. This was mid-day. When I looked at the cleaner and the weird little nook spot, mixed with the music, something odd just clicked in my mind. It was mildly intriguing, but also felt like some weird violation. I'd never felt that feeling before and from that moment on, the basement was a creepy place, where I was truly afraid (into terror), of being there by myself.
Absolutely nothing happened, that I was aware of, that justified such a reaction from me. I can't prove to anyone nor to myself that anything spiritual happened, or anything evil happened.
I think that 9 times out of 10, we project evil and good on what is actually happening. I've watched a lot of Ghost Hunters and there are startling scenarios that even get the pros having to collect themselves, but even they will admit that it was a startle and not some evil entity threatening them.
It may be more compelling and interesting to learn about the projector's psychology, in such situations. Like in my case, I'd love to know what actually was developing in my young mind. Was it some growth spurt in my brain that happened to get caught in the middle of odd stimulation?
Ok, babbling officially complete.
