Lost?

I watched last two week's episodes of Lost and I am in shock! So are we leaning more toward the dream theory...or is this just a plot turner into something else? Trev is frustrated because it took 5 episodes to finally discover what we already knew about the man who claims to be Henry. I think it could go in with my theory that someone or something picked the people on the flight to be part of a major experiment. Those of you who watch Lost, what do you think?
