In this story there is nothing supernatural about any of these things. They may be things that are as of yet unexplained, but just because we don't understand them yet doesn't make them paranormal. Just like there was nothing supernatural about flying before we understood how it works. It's just physics we haven't figured out yet. Paranormal are things that are by definition outside the explainable universe. It's not that we don't have an explanation, it's that they are by their very nature unexplainable.
