The return of the repressed

Taken from: en.wikipedia.org/wiki/Psychological_repression

Psychological repression, or simply repression, according to Sigmund Freud's psychoanalytic theory, is the involuntary psychological act of excluding desires and impulses (wishes, fantasies or feelings) from one's consciousness and holding or subduing them in the unconscious. Since Freud's work in psychoanalysis, repression is now accepted as a defense mechanism by psychoanalytic psychologists; however, there remains some debate as to whether (or how often) repression really happened and mainstream psychology holds that true repression occurs only very rarely. The way this might relate to the horror genre is when a killer returns to a place from their past e.g. Mike Meyers returns to his house in Halloween.
