There is an entire little ecosystem/subculture around "repressed memories" doing a lot of harm to vulnerable people. Basically you go to a "therapist", they do some sort of hypnosis/interview session where they ask you a lot of very leading questions, and then you leave having been convinced that your family or a satanic cult abused you as a kid (or in some cases that you have been abducted by aliens). The person performing this interview might not even be aware they are doing anything wrong, to them those leading questions ("Do you see anyone else in the room with you? Look closer, are you sure?") may just be how you get to the truth.
