This may seem like an odd question, but I think it is a good one to consider. For, at times, it is possible that when we encounter haunting we might not be aware of its effect on us.
Many of us have heard, or even experienced, that when we encounter “spirit” a tingling sensation or goosebumps may arise for some people. I believe this to be true for many of us. After having had my own encounters over the years, dating back to the 1990s, I began recognizing when I am within a “presence,” at times. I have felt this in my own home, when attending certain churches (in the past), and while attempting to communicate with ghosts at haunted locations. So I am trying to say that there has been a wide variety of places and experiences that seem similar to me (as it relates to feeling “an unseen presence”).
Others, though, have had deeper experiences with ghosts, having felt dazed or out of it after encountering what they can only believe to be a ghost attack. Now using the word “attack” seems harsh, to me, because who knows what really happened. Perhaps the ghost didn’t have intentions of attacking another person at all. So let’s be careful about labeling such experiences as attacks, demonic, evil, nasty, etc. Let’s agree to call these feelings that we do not fully understand as “odd.”
Kathryn Johnson had such an experience when entering the door of a notedly haunted place in San Diego – the Whaley House. She didn’t expect to feel the way she did, and I do not believe she felt she was attacked. Her suspicion is that, maybe, a ghost passed through her (see Whaley House Ghost Experience). And why couldn’t that be the case? After all, it might be good fun for a spirit to make their essence known by walking through or near a person. I would want to try it if disembodied, I think!
This idea of another’s spirit mixing with our own does seem parallel to accounts we hear of ghost possession (or “attachment”). People who have suffered such encounters struggle to be in control of their body and mind, seeming foggy or pushed back out of the way. Quite frightening to hear about but a phenomenon that has been known about for thousands of years.
This subject is definitely something to ponder: the influence of ghosts, invisible, upon the living. How might they affect us if interacting with us? Something to consider…yes, indeed.
