Ok, I did a quick search & according to AI: Scientifically, it’s the brain and body rapidly processing patterns and past experiences below conscious awareness (including real gut–brain signals), which is why it feels like a sudden “knowing.” It feels mysterious because it bypasses logic and arrives fully formed. Intuition is most reliable when the nervous system is calm; in trauma or anxiety it can be distorted by fear rather than true insight.

Good question. I’d love to hear the science perspective on this. Might have to ask AI!
