I woke up in the middle of wisdom tooth surgery. I was completely paralyzed except for my eyes, and I woke up right as they were sawing a piece of my jaw out. I could feel the saw in my mouth. And they had sunglasses on me, so they couldn't see my eyes. Luckily, a nurse must have seen my eyes, because I remember her saying "he is awake" and giving me more anesthetic. Luckily though, unlike you, I didn't feel any pain, just the pressure. But even that small experience has given me some really bad doctor anxiety.
