Oh, dear. That's a nightmare of mine. Sorry you had to go through that. I had 3 bony wisdom teeth extracted with iv sedation and gas. I came to mid-extraction. I was pretty scary. I couldn't talk. I could feel what they were doing in my mouth. I remember moving my tongue and jabbing it with an instrument. I heard them listening to music and chatting about a magazine article. The oral surgeon said she thought my nose was itchy, and suggested someone scratch it for me and then I was out again, thank goodness. I think you're right- you should have been unaware.
