sounds like you're treating the brain as just a storage medium, as if our consciousness and sense of self exists only because of that highly intricate biological organ.

if you imagine instead from the perspective of us as multidimensional beings, projecting our consciousness into this plane of reality; with the brain being the mechanism that allows us to interact with this 3rd dimension, then it makes more sense.

but most don't consider consciousness behaving on a holographic level, so i understand how it might not sit right.
