Nolan has said that there is indeed one explanation in Inception. I started out thinking it was all a dream and had many reasons to believe this. In fact, I could probably come up with 50 or more premises that back up the dream argument. Here are a few off the top of my head:
1. Cobb and Cobol - dreams can elicit blended associations
2. The top is Mal's totem - Cobb can't trust it
3. Repeated dialogue such as "leap of faith" and Cobb's tone when he says "waiting to die alone" to Saito in the 1st layer
4. While looking in the mirror, Cobb seeing Mal in "reality" after apparently waking up from the dream in Moombasa (and of course the fact that we don't see him successfully spin the top)
5. The characters standing around Cobb at the immigration check - why would the airport let Ariadne, for example, hang out by the other immigration agent when there's a long line?
I could go on and on. After having read the evidence for reality, however, I'm convinced that it is so. There's no need for me to list the reasons for reality, as most of you are well aware of them. Predominantly, the most obvious premise for reality is how the top begins to wobble at the end. A top that will continue to spin would not wobble like that.
Anyways, the point of this post is to point out Nolan's genius. A main theme of Inception is not being able to trust what you know (Mal: "what do you believe? what do you feel?). Once doubt starts to creep in, a slippery slope can send you to psychosis. Not only did Nolan implement this into the plot, but he did it to his own viewers. The critical, informed viewer knows that Cobb is in reality at various parts of the movie, especially the end. I think Nolan makes this extremely clear when you consider all of the evidence. And yet, he designed the dialogue, plot, character development, and visuals in such a way that you can't help but consider the dream argument. Nolan filmed the movie in such a way as to blatantly tell you it's reality but to leave just enough doubt for those who are willing to entertain another explanation.
Nolan incepted us by planting the idea that the ending may not be reality, even though it is.
