There's still a lot to figure out but we can phenomenologically and cognitively grasp the structures of consciousness by the use of drugs and modern science, which leaves very little room for the remnants of christian dualism, whether as 'the hard problem', 'panpsychism' or the trans-/consubstantiation of the eucharist.

Maybe there is a demon in my head giving me the illusion of reality being perceived as a projection on the cerebral cortex, and it's reliable malleability under caffeine, MDMA, LSD, cannabis and so on. If so, I find this model of better utility than going with vibes and prayer and belief in eternity and so on that comes with the descendants of christian dualism in liberalism, 'panpsychism', analytic philosophy, &c.

Edit: Kierkegaard wrote quite interesting texts about the structures of consciousness, I'd recommend The Sickness unto Death as a start. It has some of his best jokes.
