I, too, like to re-experience past traumas.So just to clarify, she'd like the ability to rewind her life so that she can re-experience trauma that she's "subconsiously" forgotten about.
Really, though, this tells me she's still trying to search for the "root" of her troubles, the crux of what she is. Surely, there has to be something buried deep in her past that will explain all of this. It's not like there're hundreds of people telling her what she needs to do to change. I'm sure she'd love to find out that her mind had repressed a molestation all this time or whatever.
Someone who's been traumatized doesn't go looking for trauma. More often than not, they want to stay as far away from it as possible.
