Postmodern Elements Of Inception

Intertextual references:
-Beginning and the end of the film are the same (waking up in the sea, meeting with Sai Tao).
-Characters 'waking up' in the sea.
-Safe code, room code and females number are all the same.
Paradox:
-Two conflicting ideas that cannot co-exist e.g. the neverending staircase and not knowing if they are asleep or awake.
Textual reference:
-Hospital bed at the end of the film similar to Space 2000, meeting God/creator.
-Five different grand narratives within the film that interconnect, each using a different genre e.g. sci-fi, action etc to make a new film. This makes it postmodern.
-Questions what time is, as time is not linear. Everything has already happened, it is a fallacy.
-Hyper-reality: questioning what is real (dreaming or reality).
-Simulacrum
-Depthlessness: everything in postmodernism has no depth.
