  [color=white]I don't think the island is literal at all - I think the island is the main character (Paul?)'s mind. He's filled the island with strange writings, drawings, and objects that are all representative of this major event (The Accident) and his life aftewards. This theory clicked for me when I saw the cars sunk in the water when you're in the caves. There's no way those cars got there - so it strikes me as a dream/coma thing.
