I can't help wondering if little amy is somehow 'imagining' this whole universe .
in the first episode we see evidence of all her childhood games/dolls involving the Doctor who she waited for her whole childhood .
River says they're all in a fairytale , the Doctor seems concerned that it's all about amy etc. and there's the crack in the Universe with some huge eye watching it all .
I'm not saying it's all a dream , but perhaps somehow little Amy is 'seeing' it all and continuing what she thinks is a game with all her own role-playing toys etc.
