I AM JOHN! said:I'd consider that more of a screenplay problem than a direction one, though. I think it's the screenplay's job to acknowledge that dreams are random and chaotic and not just explain everything away as if you're too simple and might get lost in all the ridiculousness of everything, not necessarily the direction.
The dreams in Inception were purposefully designed not to be random and chaotic like typical dreams because the subject has to think he's in the real world, and that's why you have architects and people specifically stationed at different dream layers, etc.
It's literally their jobs, so the dreams they invade/create can't by definition be all chaotic, because how could anyone hold a profession where they govern pure, random chaos? There's a very distinct process to the whole thing - the screenplay can't acknowledge something that would contradict it.
