Research: Sigmund Frued "The Uncanny" and Sadistic Voyeurism

"Uncanny":

Mysterious; arousing suspicious fear or dead; uncomfortably strange: "uncanny sounds filled the house."

The psychological concept of the Uncanny was developed by Sigmund Freud in his 1919 essay The Uncanny where he describes the concept as something is familiar to us becomes foreign and frightening. Freud specifically relates an aspect of the Uncanny derived from German etymology, the adjective “unheimlich”with its base word “Heimlich” which means secret or hidden.  According to Freud, the Uncanny is what unconsciously reminds us of ourselves, of our repressed impulses for example uncanny monsters. 

Sadistic Voyerism:

Voyeurism is the sexual interest in or practice of spying on people engaged in intimate behaviours such as undressing. The act of voyeurism may include the voyeur to take pictures or videos of his participant. Sadistic voyeurism however is when the voyeur gains pleasure by inflicting pain on the participant which they have been on looking.
