I agree it was kinda silly, but seeing as how the entire movie is about things that go beyond reality - I gave it a pass. At least it wasn't a common ending. My interpretation, as far as I bothered to have one, was that the woman allowed him to be reunited with his wife, because he helped her find her son. Makes sense to me, anyway. That said, it doesn't quite make sense that he was so laid-back about being obviously dead.
