I think the most disputed idea is his belief in repressed memories.He thought that when traumatic events happen, we bury (repress) the memories of them. Usually, the opposite occurs and we can't get them out of our mind. I,ve treated many people with symptoms of Post Traumatic Stress Disorder and although they are often reluctant to talk about their experiences, when they do so ,their memories are perfectly fine. In fact, people with PTSD tend to re-experiene the traumatic event over and over in flashbacks, daydreams, nightmares, etc.
