Guys, I'm kinda curious about an aspect of Lost that you've been discussing here. I don't follow it as closely as you guys do, I decided to just enjoy it and watch it weekly without dissecting it too much. I'll just keep on with my simplistic interpretations.

But one aspect about this series has kind of been in the back of my mind since the first we saw Jack open his eyes on the island. There's that sci-fi/fantasy element going on here. Yet the show doesn't always cross that line in such a definite way. Well, now it seems to be with Locke/MIB transformation.
I know from interviews that JJ Abrams is a huge Twilight Zone fan.
I can't help but wonder if on the last day of the series, we'll see these passengers wake up in an Air Force training mission and realize they've all been in a dream or this has been some kind of mindgame they've been experiencing to test them. That is of course a Twilight Zone plot and twist ending.
