Concept is too nonsensical and illogical, how can someone have multiple dreams within a Dream?? The story of the movie is that, to plant an Idea in a CEO's mind, a group of People Dream within the dream, again dream within the second dream and within the second dream they dream third dream. Movie ending is ambiguous, it does not give the clarity if everything happened in real or in Dream . This is indeed one of the most overrated boring movie ever.
