Neat, that's legitimately interesting! Maybe you have something unique in your physiology that gives you a different perspective? I'm pushing 6 surgeries under general, and around 5 precedures under IV, probably missing some numbers with my now shoddy memory forming capabilities, but my experiences with the knockout sedation could be described much more similarly to your experience, and a few of the IV sedations weren't as deep, so I remember a bit more of the "in and out", but mostly it's just "Oh, yeah, I feel there's a change in my coherence-BLACKOUT", and then next awareness is recovery room beeps.
