I haven't seen anyone talking about this so I thought I would share this insight, if this helps someone then that would be great. Enlightenment or any kind of awakening doesn't happen within the dream. By "outside the dream" I don't mean some other dimension, but Absolute Truth itself. In earlier enlightenment experiences you may get glimpses of Absolute truth, but thats not exactly the right way of expressing it. It is more like Absolute truth is glimpsing itself. In enlightenment, enlightenment becomes enlightened,  not you. The false self cannot pass through the gateless gate, not even a microscopic inch of it.  My point is that you are not working towards enlightenment. You are letting enlightenment become enlightened. Dream exists within duality. Non duality(Absolute Truth) cannot exist in duality. This includes you and the world. Only Absolute Truth remains because its the only thing that is true. Hope this helps
