Bible or any written text has meaning. Let's say we take the most ungenerous position and consider it as willful psychological manipulation of masses. Does that deprive it of 'meaning', 'agency'?

"Logical fact".

I missed this bit in your argument. Presumably, you assert that the mind's modalities consist of a 'rational' state of consciousness and a dream state mode where the content matter is "random". It is true that the mind, unfettered by the necessity to navigate in real-time a physical reality, is no longer constrained by either physics or causality. This then results in content matter that can seem random (as narratives) but to deprive them of meaning does not follow.

    I saw in a dream a table where all elements fell into place as required. 
    Awakening, I immediately wrote it down on a piece of paper, only in one 
    place did a correction later seem necessary.
