I know it is a lot to take in. I've found it helps to take things in steps. Focus on the amulets and settling for now. Handle the reality of demons and Lucifer after you've begun to feel comfortable with those.
As I said, you'll find all kinds here. Many of us have abilities. Some of us have technology that many would consider to be science fiction. We have time travelers, teleporters, fliers, all sorts. I myself have an innate understanding of the quantum nature of the universe, which allows me certain abilities similar to teleportation. So far, none of us have found a way home.
