The movie stars to be the most dreaming one that I have ever seen.The director nolan creates a dream world that is very impossible for us to imagine as I have to see the the movie thrice to deeply understand the hidden concept of it.The main role done by Leonardo dicaprio really invades the subconscious minds of the characters in the film and also the viewers.
Dream within a dream is itself a higher imaginary concept, where actually higher level of four is been shown in the movie.Dicaprio also say that the idea that created itself can be called as a virus as it is a parasite that will be hidden in the mind of us as the reality can never be reached then.
