View the film backwards. She is a normal girl, just a stupid American tourist who was raped on a ramble. This caused some major disassociative problems and she felt like she was an alien in her own skin. She tries to re-establish a romantic connection with her boyfriend but find that sex is now much too impersonal. She just can't do it. So she reverts to hypersexuality as a way to deal with rape (common enough) but this escalates to murder because she is driven by her own need to reclaim some kind of power. Her doting boyfriend does his best to help her but even he eventually has limits and she is left an entirely broken human being. A complete alien clothed in human skin.
