I think it is more related to Descarte's philosophy of "I think therefore I am." A brief synopsis: Rene Descartes was taking a nap in which he dreamed that he was having a dream. That is, a dream within a dream. During his nap, he awoke from one dream only to realize he was still dreaming. He asked himself how do I know that I am not dreaming right now. Through some circular reasoning he came up with "Ergo congito sum (sp?)" or I think therefore I am. It doesn't matter if we are dreaming or not, our thoughts are real. The W brothers take this philosophy to the next level and give us a vision of what waking up from a very real dream would be like, somewhat like pulling the drapes back on Descartes version of the Wizard of Oz. Mix in some Eastern religious, messianic, and gnostic themes and you have a movie that is thought provoking on one side and blatantly philisophical on the other. Christian themes can be found, but they don't seem to be as intentional as the overall philisophical push.
I still haven't seen the last installment, so don't ruin it for me. Just imagine if Neo wakes up at the end and realizes it's all a dream. Wouldn't that make quite an ending.
