And we applied that process in the first half of the film when they're doing the sort of darker fantasies. And then when we go to the second half of the film where it becomes more about sort of like coming to terms with your past, it shifts to normal color, you know. And then at the end again it goes back to the original look. It means a lot of things. Death and rebirth.
Water is a metaphor for spirituality and rebirth.
Because I actually see this film more about rebirth and living than I do being about death. As opposed to waiting around for it to happen for you. Terry says I don't dream. And by the end of the movie he's absorbed a bit of Nick's ability to dream.
