"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.

As the saying goes, YMMV. /gThe bible is trying to communicate, but it is not a factual piece.
That does not map to my experiences with dreams and their content. But then, I -- my conscious self -- do not take an adversarial position regarding my inner Self. I benefit from reflecting on my dreams, otherwise I wouldn't waste my time. Integrating unconscious psychological content of my mind has always been a positive event, and promotes psychological health, stability, maturity, and (believe it or not) insights.
YMMV.
So my claim is all the benefits are created by your conscious self, but you perceive it to be from the dream. Similar to how religion helps people. Both are fiction.
The burden of proof is always on the person assigning meaning to something. Why? because from a probability standpoint, no meaning is more likely. So the person claiming dreams have meaning must prove why their claim is real despite the low probability.
Why is meaning low probability? Because much more things in the universe have no meaning then have meaning.
For example, greek mythology. I know nothing of it. Yet I can make the claim that it is false and have a higher probability of being right then the person who claims greek mythology is real and has meaning and knows everything about it.
The majority of "meaning" is "found" the same way a christian "finds" meaning in the bible. It is common human behavior. By making a claim that someone has found meaning in some random thing this way, I am making a high probability claim because of the fact the behavior is so common.
