Wow, that's an intense experience!
I can't say I've woken up from surgery per say but pretty darn close. I had two of my wisdom teeth removed a few years ago. My Mom sprung for the "good meds" aka getting twilight anesthesia while they were doing the procedure. It's not technically a local anesthesia but it makes you fall asleep and feel no pain. Some where in the middle of it I woke up, became conscious, felt no pain,
very little pressure/movement, but I
heard the doctor and nurses talking! They were totally chit chatting like it was no big deal, talking about their plans for the weekend! I remember being rather offended they were taking the entire procedure so lightly and then next thing I knew I was waking up woozy.
