I read the article in the first link.

I recognize much of it from when I was a 'believer' (theist). Not that I was doing any ghost hunting, but I had one poltergeist experience, and felt uneasy in that house then after. But at the time, I was easily impressionable. One of course was because of young age, but belief was just as big a factor. I was constantly warned by my overly religious mother about demons and how dangerous 'playing with the occult' was supposed to be.
Which of course, combined with paranormal / supernatural belief, makes rather mundane, everyday occurrences turn into something more. Tricks that are played on your mind by for instance optical illusions will settle as an otherworldly experience.
When I stopped believing in the supernatural, I remember vividly that everything became a lot more 'quiet' than before. Hard to explain. I suppose a believer would liken it to an exorcism or 'cleansing'...
The only times I get an emotion that is comparable at all nowadays, is if I get scared by a paranormal horror movie (very rarely now), or if I'm in a pitch dark cellar or something. But I'd say that (the latter) is rational, in the sense that fear of the dark most likely is an evolved thing. I suppose one gets eaten less frequently(!) if one is jumpy and alert in darkness than if not.
I have some experience with the New Age types as well, and to put an example to what I said about mundane things turning into something more, I once saw a photo posted to Facebook of a meeting a few of these people had had - adult people - and on that photo, you could see
so-called 'orbs'. Now, in all seriousness, these 'orbs' were said to be spirit beings that they had captured on film, and they were all excited about it. I think that if one
wants to believe, these things happen.
All that said, I'd be happy to go ghost hunting with you. Or... "ghost" hunting, as I would probably call it.

I'd like to revisit the house I experienced that poltergeist for instance, because I think I have figured out how/why it happened.
Unfortunately I can't. Or at least, it would be very awkward.
