Thriller genre includes spooky stories involving ghosts, zombies, vampires and the supernatural or the paranormal.
The terms “paranormal” and “supernatural” are often tossed around to mean the same thing—something we don’t understand. They’re actually two separate terms, though. “Paranormal” refers to something that’s not understood by current scientific knowledge; there’s the potential that something paranormal will someday be explained scientifically, and there’s a likelihood there’s a good, natural explanation for it. “Supernatural” refers to a phenomenon that is beyond our capability to understand, now and simply forever, because it just doesn’t operate under our rules. http://knowledgenuts.com/2014/02/20/difference-between-paranormal-and-supernatural/
