These are all spiritual beings that can be seen as an apparition, especially in woodland areas where the veil is thin. I have been to about three woods (Thatcher, anything around the Desplains River and Midlothian) that make it nearly impossible to tell what is physical and what is spiritual. Especially when most covens and cults perform their rituals in these forests, it creates the perfect recipe for thinning the veil and empowering such beings. In the particular woods I mentioned, I would NEVER recommend going there alone, I went there with a retired Navy Seal. There are Satanists in those woods that make the Satanists here look cuddly. Police don't even go into those woods alone because people have gone missing and when some of them are found...well let's just say the last body had no hands. I saw a dog there dead with it's paws and head cut clean off. Illinois woods don't play around!
When I became a mom, I stopped going on my hikes through woods around sunset and late night, but I lived around them without a car and many times had to walk alone down empty streets with the woods on both sides of me. Not a fun feeling, and I saw and heard many disturbing things, but I had no choice. But you can bet I was chanting a protection the entire walk!
