I think that goes a long way to making my point. A bunch of people believe in supernatural things, but don't talk about it because they don't want to be teased, and I'm not just talking about religious beliefs. In 2017, only about 25% of Americans said they didn't believe in ghosts, according to one poll.
But then you have other people who not only believe, they will go to great lengths to tell you about their beliefs or tell you their story of supernatural encounters.
I used to work with a person who; during an after-work converstaion, went into great detail about a ghost encounter she once had and why she knew it wasn't a hallucination or a prank. This dispite the fact she had previously told me she had been a heavy drinker and drug user at the time of her encounter.
Just this past Summer I met a man who is retired, whose hobby is to travel to various parts of the country with large forrests where he finds animal trails and places video cameras, set to film in very low light conditions and has them set up to start recording when motion sensors pick up movement. (He must have lots of recordings of possums, owls, coyotes, the occasional mountain lion or bear.) He collects animal fecal matter and sends it to labs for DNA tests. As you might guess he's looking for evidence of Bigfoot. (As a side note I asked him he if was part of that TV show (Finding Bigfoot, I think) that looks for Bigfoot. He was somewhat dissmissive of the show but he didn't go into details and I didn't press him for his reasons.) He told me and several others; this was at a dinner party, that just a few weeks before he was in a forrest (in Kentucky, I think) where he was out at night checking his cameras and a Bigfoot came up right behind him, "I could feel his breath on the back of my neck." He said a friend who was helping him, came looking for him, calling his name and the Bigfoot ran off, and even though he spun around to take a flash picture the only thing his cell phone camera got a picture of was disturbed leaves moving on low hanging tree branches. He told us that he was next going to someplace in the Pacific North West to check out the latest "convincing" sightings he had heard about.
(I didn't laugh and I was very polite; because you never know how a mentally unbalanced person might react if you tell them that you doubt the CIA has satellites that can look inside their head and that can secretly control them. However, I did say he was lucky it wasn't a bear that had come up behind him, because black bears aren't usually agressive but if you were to incur on their territory or if they felt threatened things could go bad fast.)
Anyway the point I want to make is that while fewer people may say they believe in things that go bump in the night, the ones who do can be very vocal about it. Plus, with the internet, cable TV and social media, it's easier than ever for these people to spread their messages of experiencing supernatural encounters.
