“From a spiritual perspective there is a different reading again. This movie is one with a profound spiritual idea at its heart, for those interested – just as with ‘The Matrix’, and Guy Ritchie’s ‘Revolver’. In ‘Inception’, Nolan seems to be using the metaphysics given in ‘A Course In Miracles’, a seminal spiritual text from the 1970s that was purportedly channelled from Jesus and which continues to profoundly influence modern spiritual thinking. In ACIM the key idea is that what we think of as reality is in fact a dream – that there is no difference between the dreams we see at night, and what we see with our eyes open. Both are projections of our mind, which is trying to escape a core guilt by projecting guilt outside of itself onto projected ‘dream figures’. [spoiler](For more on this see the FAQ titled ‘If the spinning top really did keep spinning at the end…’). Thus, although Cobb returned to ‘reality’, Nolan seems to be making the point that what we think of as ‘reality’ is still a dream. And, that within that dream, we see what we want to see – projection makes perception. Thus, the movie is devised so that some viewers look at the spinning top and see it as being about to fall over as the movie ends. They decide that the movie is saying that Cobb is back in ‘reality’ and not dreaming. Others see the top as going to continue spinning indefinitely. But, one then inevitably asks, how could Cobb be still in a dream? Which leads us to think hard, to debate, to share ideas, and perhaps eventually to question the unquestionable – that ‘reality’ is not what it seems to be. Nolan is cleverly sowing a key idea in our consciousness. So you could say the movie Inception is in itself… an inception! Within this interpretative framework, Nolan is reaching to us within the ‘dream’ that we call reality to help us to start to challenge our assumptions about ‘reality’ and begin to wake up – just as Cobb went into limbo to get Saito.
Yet for an inception to work, one must accept it as one’s own thought process… so of course Nolan does not give interviews where he says, ‘This is a movie where I’m trying to wake people up to the fact that they’re dreaming’.”
