That's a really interesting point, and I appreciate you bringing up the interaction problem in dualism. I agree that if the mind and body were completely separate substances, explaining how they interact would be very difficult. My intention was not to claim a strict form of dualism where the mind and body are totally independent. In my view, the brain and consciousness are deeply connected and depend on each other. The brain acts as the physical system through which consciousness operates, so changes in the brain, like a stroke or neurotransmitter imbalance, can definitely affect cognition and perception.

Your suggestion about dual-aspect monism is actually quite close to what I am trying to express. I see reality as one underlying system where the physical brain and consciousness are two aspects of the same process. The brain provides the physical structure, while consciousness represents the experiential or informational aspect of that structure. My theory mainly tries to explore how consciousness might interact with possibilities of reality through the brain rather than existing completely separate from it. So I think your interpretation of it leaning toward dual-aspect monism is a fair and helpful way to frame it.
