Person vs. Supernatural is when a character is battling supernatural forces. Sometimes, this force is inside themselves, it is internal. Such stories are sometimes used to represent or criticize Freud's theory of id vs. superego. Bram Stoker's "Dracula" is a good example of this, as well as "Frankenstein" by Mary Shelley and "Christabel" by Samuel Coleridge. It is also very common in comic books.
