The feeling that the true life is elsewhere, that there is something to be sought, something that eludes you, etc., but not something other or out-there rather it is what is beneath you, what the roots of your mind, your entire living, are sunk into, roots that go so deep and spread so far that they are indistinguishable from the soil. If you see it this way it is easy to see that nothing distinguishes waking life from a lucid dream, except that in the dream you are filled with wonder as to how this marvelously articulated world came about and you feel a mysterious kinship with the unknown source. And of course nothing but your habits of thought prevent you from having just the same feelings about reality. No reason they shouldn't be even stronger. The problem is that you confuse causal priority with ontological priority. The experiencing is ontologically prior to the experience, but the cause and the effect are on the same ontological level, they both belong to the experienced. So if you mess with your brain your experience changes. Fine, but your brain is just something you experience in a certain (indirect) way. the same goes for the whole weight of causality, whatever it is and however far it extends. The experienced needs norms, and norms need to be pretty firm. The more you chase them up the firmer they become. None of that has the least bearing ontologically, there is no conflict, nothing that need shake the other, the softer and sweeter kind of certainty.
