Q: I just watched Pan's Labyrinth last night. The movie is really good, but I could not understand one thing - the fantasy part with Ofelia, is it happening for real or she is just imagining things? I ask this because I noted two points in the movie - When Vidal pulls the mandrake root out of Ofelia's mother's bed it appears to be just a normal root. While whenever Ofelia is seen with it, it does things. In the end when Vidal follows Ofelia to the labyrinth, Ofelia is talking to the faun, but when Vidal looks at it, it appears that there is no one there. So what's exactly happening? Is Ofelia just dreaming things to get herself in a fairy world, out of her present surroundings or the things happening for real but visible only to Ofelia?

What is going on in Pan's Labyrinth?
