My take is that "the island" is appearing as Jack's dad and Claire, they're both dead. Jacob too is an apparition, perhaps one of the black rock crew. Then we see Jack's father appear in a flash forward, which makes me believe the oceanic six are really trapped in some kind of a fake reality. This show always keeps you guessing and that's why I love it. People who don't apreciate that kind of mental activity cry a lot when they watch Lost.
