No filme, parece que isso é deixado intencionalmente um mistério. Para citação Emmanuelle Seigner , a atriz que interpretou Vanda e a esposa do diretor:
We don’t know. Maybe she is from his mind. Like in Rosemary’s Baby, at the end you can think, maybe she dreamt all that. Or maybe she is a goddess, or an actress that wanted to teach the director a lesson. Who knows? I like that it is open and mysterious.
No entanto, em uma entrevista com o dramaturgo, David Ives , ele parece indicar que Vanda é uma pessoa de carne e osso.
...like the fact that Vanda [the character] is an army brat and Nina [the actress] really is an army brat.
