I mean, wow.
This is a lot like that time I was traveling through Chicago and overheard an American soldier in O'Hare airport tell his compatriot, "We saved their asses in world war II, why ain't they helping us in Iraq!?"
I mean, sure, I knew that this sentiment existed, but it's still a shock to hear it expressed.
But this particular thread is full of ignorant, naive people claiming to have experienced ghosts. Now I know that Huffington Post is a gathering place for all kinds of woo, from the anti-vaccination crowd to homeopaths, but it's still powerfully strange to see so many of these people in one place. It's enough to make me fear for humanity.
There are no ghosts. There's never been any convincing evidence for ghosts. They either turn out to be the result of pranksters (think "crop circles"), the result of dreams or hallucinations (especially the night-time experiences) or outright fraud (the medium who kicks the table). No one has ever presented any evidence that could withstand the light of scientific examination.
I know. The pro-ghost faction are now going to say I'm closed-minded. I'm too skeptical. "Science doesn't know everything" or "Science use to think 'x', you know!" where 'x' is some old belief that has since been corrected. Of course science doesn't know everything, but it is the best technique we have for examining positive claims.
You claim that ghosts exist. You claim that they frequent certain places. So we examine those places for the signs you claim to see. And we find nothing.
Now realize you've been credulous and naive and find something better to do with your time.
