@Merlu i can’t say, but it’s possible, id think, given that to the brain, an event, a dream, a vivid daydream, and a movie are much the same. i can’t, for example, watch horror movies. if i do, i will have terrible nightmares. and i’m choose about what i watch (and read) in general, because for me, it’s like i’m living it. there are things that still evoke feeling from me 60 years later—that didn’t actually happen to me. (oh, and a lot of things did happen too, and i have ptsd, diagnosed, but i probably didn’t have it my whole life.)
oh, if you just mean “it horrified me and overwhelmed me emotionally” (vs actual clinical ptsd—i’m too literal sometimes, and i don’t know how to edit or delete on kbin yet so…) then for me, that would be a number of movies, but probably the worst would be blue velvet. dennis hopper’s portrayal of a homocidal maniac was just too, too much. i wish id never watched it.
