Horror films have always been supported by a group of loyal audiences. According
to the Freud's theory, the ghosts on the screen is an unconscious projection, which
reflects the castration anxiety and fear of death. Freud (1919/1955) points out
that people depress the castration anxiety and the fear of death in their hearts.
The castration anxiety is presented as broken ends or dismemberment. And the
ghosts can arouse the most intense fear of death. Japanese roboticist Morihiro Mori
(1970) put forward a "uncanny valley" theory, claiming that the body, or broken
hand, is terrifying because it blurs the boundary between man and non-human.
When the human body "defamiliarization", the relationship of "human likeness"
and "affinity", to create a "uncanny valley" on the graph. Director Yao Feng-pan of
Taiwan's "King of Ghost Film" has many images of "human defamiliarization " in
his horror films. This study takes the theory of "Horror Valley" and quantitative
approach to explore the causes of the horror brought by Yao's horror movies.
