"Folk horror is a subgenre of horror film and horror fiction that uses elements of folklore to invoke fear and foreboding. Typical elements include a rural setting, isolation, and themes of superstition, folk religion, paganism, sacrifice and the dark aspects of nature. Although related to supernatural horror film, folk horror usually focuses on the beliefs and actions of people rather than the supernatural, and often deals with naïve outsiders coming up against these."

I think there's a variance in what different anons are considering folk horror
