Return Of The Repressed

Our teacher asked us to research the phrase "return of the repressed" here are my findings:

"Return of the repressed" is the process where repressed elements tend to reappear. In context of a horror movie an example could be Halloween where Jason leaves home at a young age after murdering his sister as a child. He then returns years later (when everyone has forgotton about him; as his actions have been repressed)and begins a killing spree.
