Let the mystery be. We don’t get the logistics of how it works but it was absolutely real. Maybe you’re having a different conversation here. My point is that whatever happened isn’t some figment or dream where “it was all in is head” or doesn’t have some tangibility. When he died he was very much transported somewhere and this same place is where the guy who says he’s god was also transported and there’s actually other characters that mention the place. Who knows what it truly is but it very much is real.
