You guys are arguing over nothing. Nolan himself said he made it so you'll never know if it was a dream or not. Give up. He soprano'd you. Hes a fakkit.

But it’s not a mistake. I put that cut there at the end, imposing an ambiguity from outside the film. That always felt the right ending to me — it always felt like the appropriate ‘kick’ to me….The real point of the scene — and this is what I tell people — is that Cobb isn’t looking at the top. He’s looking at his kids. He’s left it behind. That’s the emotional significance of the thing.”
