Good point Zen, that is how I saw the film too. My girl said the bit about the space scenes being his internal voyage too; like it was so obvious. To me that is like saying that Total Recall doesn't have two interpretations because the guy had a sweat drop running down his face, which proves that it WASN'T a hallucination.
I liked the film, and prefer to imagine that he planted the magic tree over his dead wifes body and it picked up her essence and he was trying to get her to the nebula so they could be reunited when the star went nova.
