Question: What is the significance of the man in Hell who thinks Chris is his son?
Question: What is the symbolism behind the upside-down cathedral?
Answer: It's open to interpretation, but one theory might be that Chris' faith and his assumptions about the Afterlife have been completely "upended." And as Annie has lost her faith altogether, he must now struggle to bring her back into the fold and set things right so that they can be together.
Question: Does the color blue have any symbolic significance in this film? I've noticed that blue flowers are pretty prominent throughout the film as well as Annie's blue dress and Chris' blue suit in the last few scenes. It seems like the cinematographers took special care to make all the blues really stand out.
Chosen answer: Taken from http://dreemmoods.com/cgi-bin/searchcsv.pl?search=blue&method=exact&header=symbol: Blue represents truth, wisdom, heaven, eternity, devotion, tranquility, loyalty and openness. The presence of this color in your dream, may symbolize your spiritual guide and your optimism of the future. You have clarity of mind. Depending on the context of your dream, the color blue may also be a metaphor of "being blue" and feeling sad.
Answer: Just to show what hell does to your mental state.
