In the film industry, the horror genre is a movie genre that branches again into a more specific sub-genre. One of the most interesting sub-genres of horror films to me is the psychological horror. Because through the sub-genre of this film, the audience is frightened not by the things that appear physically in the movie (the emergence of ghosts or jump-scare scenes), but by things that affect psychologically, such as the scary atmosphere or the music gripping.
