I have PTSD. I've locked out large chunks of my childhood. I first saw Marnie when I was 17. It didn't knock my repressions loose, but it certainly stirred them up. I saw it again when I was in my forties, and I was recovering my memories. It knocked my socks off again. This movie would probably play completely differently to someone with a different history from mine. But it really hit it for me, and all those years when I was holding things down, I think it let me know that I was not alone.
