You can learn the skill in a day. Most of those “paranormal” videos looks amatuerish as heck. A lot of them didnt fix the light so the “ghosts” has a weird outline that set it apart from the rest of the real video. Human memory is even worse, our brain is a notorious liar. And yes people should demand evidence and so far we have 0 empirical evidence. Those videos can be entertaining if that’s your thing. I just wish they up their editing skills a bit.
With that said I really enjoy the Cthulhu mythos. Taking all the xenophobia out, Lovecraft is a great read
