yup - "Mysterious Skin" also triggered me seriously.
but i was like Brian - the other main character - dysfunctional family - demanding, emotionally distant father figure, emotionally dependent mom. Brian was a high achiever in school who was a "good boy" and never acted out - but denied and repressed all memories into dissociative amnesia. weird thing was that like him i also had a fascination with space aliens and UFOs although i didn't use it as a cover story for my CSA.
it is a powerful film. i first read the book - then saw the movie - found them both very disturbing - hard to say which was a worse trigger. i still haven't fully processed it all.
i add my caution - be VERY CAREFUL if you think this story might trigger you. it probly will be much worse than you imagine.
