Spoiler:

Except that in internal framework of the film, the dreamer is always IN the dream. So I could imagine the whole thing is happening on Mars, and Cobb is kept in an ice-cold snowglobe while the Martian Princess dreams about him ... but since Cobb is the main character of the film and, I believe, is in every scene in the movie ... I'm comfortable with my assumption that the entire film is his dream.

Of course, one of the things I like about the film is - like life - it's completely open to multiple interpretations. I may develop a slightly different one if I see it again.






And, au contraire, I think it gives incredible depth to the movie. But that's just me (and, well, maybe a few hundred thousand other folks).
