as a kid stories of "old hag syndrome" use to scare the shit out of me.
I don't know or understand the Mothman thing.
I have some theories about the big Foot phenomenon, but nothing good enough to "publish." I do know this: If these beings exist, then they know some things that keeps them in existence. Red Elk says that they are evil, but I'm not so sure. Big Foot probably has a disdain for humans because they see what we do to nature. They also know that if they do not remain hidden, then humans will genocide them and put the rest into captivity via Zoos. They also know that some among us would eat them.
On the shadow people: I've had encounters with the Hat man in my dreams. I finally defeated him around 2007. My daughter was seeing shodow people last month. When she did, I would get there too late to have a good look. I did see something moving fast that looked like a shadow, but just a glimpse. This happened three times. I took care of the problem and now they are gone.
Brother, Brotatochip, I can see it happening to you, and you should let your mind continue to wander. You don't have to believe anything, just entertain these kinds of ideas. Once you do, and enter into the magic theatre, you are going to find all kinds of stuff for your discernment. It's a good place to visit, especially now.
