Orchestrated Objective Reduction is such a fun theory, if a bit fantastical. The whole concept of wave function collapse tickles my cockles.

Retrocausality: This concept, which arises in some interpretations of quantum mechanics, suggests that an action in the future could influence an event in the past. Some researchers hypothesize that this quantum retrocausality could be a mechanism for phenomena like intuition or precognition, suggesting that information from a future cognitive state "leaks backward" into the present consciousness.
Consciousness Theories: Some non-mainstream theories, like the Orchestrated Objective Reduction (Orch OR) model, suggest that consciousness is a quantum process occurring in the brain's microtubules. Proponents of these theories sometimes propose that the quantum nature of consciousness could lead to entanglement across time, offering a potential, albeit unproven, physical basis for precognitive experiences.

I feel like this is extra fantastical for a quantum mechanics theory, because one of the fundamental assumptions of most quantum mechanical applications is that randomness exists, and therefore the universe is not deterministic (ie, it does not have linear time with a fated sequence of events).
Intuitively, retrocausality and randomness probably can't both exist-- how could something leak back from the future if random events can happen between now and then? But then, maybe it's human bias to view time the way we do through our limited lens of only living in one slice of it, and it actually works far differently.
This was the great scientific debate in 20th century physics and frankly my favorite mystery about the universe; Einstein believed the universe was deterministic, randomness did not exist, and Niels Bohr believed the opposite. Bohr's camp is widely regarded to have been vindicated by discoveries since then, but it's a question we're still trying to put to rest even today. The 2022 Nobel Prize was awarded to a team that
basically eliminated one of the determinism folks' loopholes that they could use to claim linear time/determinism existed in spite of the supposed randomness we observe.
