The Return of the Repressed

This is a theory made by Sigmund Freud. It is about feelings and thoughts that are in the unconcscious mind of a person, like a bad memory is repressed and put to the back of the mind into the unconscious part of the brain. This is where the term 'Freudian slip' comes from. In horror this can apply to settings, as basements are the part of the house where things are repressed and monsters normally come from them.
