My boyfriend took a course that was being offered at our local community college on the topic of what happens beyond death. The instructor is a kind of a big wig parapsychologist who actually got a degree in the material when it was possible to do that. Anyhow, he teaches these 6 week courses on witches and voodoo, what happens after death and metaphysics and parapsychology. It's all based on his own research and labs at universities (back when they could find funding for these type of things). So here is a person, who is not talking about his own personal experience, but has actually done and collaborated in scientific studies with others. I only went once to his class out of curiosity and because i liked the idea of hearing about the studies and not just something anecdotal. His description of things was through a scientific lens so I thought that was pretty cool. Of course, I'm a big skeptic too so I filter things through my critical thinking brain and just listened.
My personal conclusion is that there are things that we do not fully comprehend and that there seems to be people who are able to perceive things that others cannot. I mean, is it such a stretch when you think how animals perceive differences in temperature/atmosphere/sounds etc that humans can't? anyhow, I don't know exactly how any of this works, but I just can't dismiss the evidence that is out there by claiming it all in one's head.
I actually asked why some areas seemed to have more paranormal occurrences than others- he answered it had something to do with magnetic fields. I think there's alot more to it than that too but that was his kind of basic answer.
Some cultures are obviously more open than others - the States was inhabited by puritans- this had an effect on multiple aspects (social/religious/cultural/psychological). There are cultures around the world who live quite harmoniously with a "spirit" world. I think people in some cultures might be paying more attention than others so they might catch things we would just shrug off. Of course there is the other extreme of folks who are very superstitious and attribute everything to "spirits" or demons. That reminds me of JW stuff.
What was really interesting for me to discover was that there used to be a group of scholars who were doing these experiments on university campuses which would be completely impossible to do now because of changed attitudes and perceptions regarding was is considered "science"
Here's an article he discussed in his class: http://www.newsweek.com/where-do-you-go-when-you-die-increasing-signs-human-consciousness-after-death-800443
