I had a brief episode of surgical awareness (feeling the pain of surgery while under a general anesthetic).
I had a bad experience with a spinal during my first C-section--it didn't take all the way and I felt terrible pain.
So when my second child was born, I told them I wanted a general anesthetic. I was laying on the table and my husband said--oh is she out already. I went to turn my head and tell him I was not out but I could not move, I was totally paralyzed. The surgeon started the surgery and I have never felt so much pain and all I could think was - oh my God, I am going to feel this entire surgery and cannot say a thing!
Then I was out. It only last about 15 or 30 seconds but it really left me with a fear of surgery--or not being fully out during surgery.
