Movies like Pan's Labyrinth?

I recently saw Pan's Labyrinth and I just LOVE the creepy/mysterious/unexplained feeling of the movie. The part with the pale man and the paintings of him eating the kids on the ceiling really pushed it over the edge for me. (Why are there no doors? Who painted the ceiling? Where are they? Is that sunlight coming through the windows? Were the other children all little girls that thought they were the princess?)

It's always the things that leave so many questions unanswered that get me and make me watch it over and over again, so I would greatly appreciate if you supply me with other movies that give that same feeling.

Thank you!!
