The correct answer is painful experiences.
Repression is one of the main foundatins on which psychoanalysis is based. Sigmund Freud was the first person to recognise the meaning of repressed memories. Whenever a shocking event occurs, the mind pushes into some inacessible spot of the unconcious.
Typically, repressed memories are associated to painful experiences such as sexual, mental or physical abuse.
Professoinal help is needed in order to reduce the impacts through an individual's life.
