This.Also I feel a lot of the people (not anyone in particular) saying "the ending is a dream" are only saying that because it's the edgy ending. I cant think of any reason the ending couldnt be reality, that it couldnt just be a straight foward story with a straight foward happy ending.I personally subscribe to the idea that the entire thing was a dream upon a lot of reflection (at least until I can watch it a few more times), but regardless,I'd say that Cobb's kids not having aged a day and even being in the exact same position playing as they were the day he left is a pretty strong indicator that the end was a dream all on it's own.Not to even mention how quickly and cleanly everything wrapped up in the end. It was like he woke up and everyone's there and he's home a minute later. It was just such a sped up, neat and tidy happy ending that it all seems more like a dream than an ending that actually takes place in the real world.
