I voted dream, not because I like that interpretation or think it was necessary for the story, but because Cobb's children hadn't changed a bit from his memory earlier in the film. Yeah, I know it could be symbolic or simplified for audience understanding, but children that young grow up fast, and we know he'd been on the run for some considerable length of time (long enough to get a string of jobs extracting, and to establish a reputation for himself doing so). I find it implausible to the point of absurdity for him to return home in reality and find his children looking, dressing and acting exactly the same as the last moment he saw them. Plus that top was spinning for an awfully long time...
I thought someone here said that there were actually two sets of children hired to play Cobb's kids. This is something I'd really need to watch again just to compare. Kids do grow up fast, but how much time had actually passed since the last time he saw them?
