Some people really missed the point of this. There's a key moment halfway through which if erroneously interpreted would lead to some very negative reactions about the film. I saw this at a festival with the director present for Q&A. He seemed alarmed at the interpretation of some people (as did I) about this event. My advice is to accept what you see as truth - not as a dream or a fantasy - and then it will be clearer and you may actually end up enjoying this and feeling satisfied, as I did.
