It may also seem corny but to someone who's lived through it, the scene in Harry Potter and the Prisoner of Azkaban in which Harry saves himself but thinks that the spirit of his father saved him, also speaks to the confusion of trauma. Who saved me? Was it me?
I'm not sure why saving oneself is paradoxical, but it is to a child. I'm glad J.K. Rowling wrote about this paradoxical feeling. It's also a classical theme in American Literature, "Be your own father." Independence.
