During the snow dream, Eames (the guy who masquerades as others) is going around killing people and drawing attention away from Saito and Fischer as they make their way to the compound. At one point he falls about a dozen feet to the ground off a ledge, and the black guy who pushes him off jumps down. They wrestle for a little bit. You see the black guy's head on the ground, as Eames is on top pummelling him. The movie splits to another scene, then comes back to Eames/villian. Only this time you see a white guy's head with Eames. Another split to a different scene, then back to Eames/villian- this time a black guy. The thing is, I thought that maybe the white guy was a mirror image of Eames- as in, Eames is fighting Eames. It does look like he temporarily halts his pummelling and has a shocked look on his face for a split second. Was this just bad editing for that one second scene, or more to it?

I'm pretty much of the mind that his wife was right. They were still asleep. Notice that to get to the "shores of the subconscious" you needed to go down more than one level, but he and his wife only came up one. The father in law's "come back to reality", the comment by Eames about "you're going to use his own subconscious to attack itself", the moment towards the end where his dream wife makes the statement about his beginning to doubt it all, and the moment Ellen made the bridge out of the mirrors....I thought the movie was a rescue mission to pull him out of himself and Ellen was actually his wife. That the entire movie was a multilayer gambit similar to the one they were playing on the mark from DiCaprio's vantage point, but actually on him and designed to wake him up.
