I think I have to clarify something. The whole thing was not as bad as it sounds. I had a local anesthesia in my arm (which was operated) and was sedated with propofol (i think). My focus wasn’t as much on waking up, which i guess from the comments can just happen. It was more on my inability to speak up if something is wrong. Maybe they even noticed, and thought its alright. There wa no pain, just an unsettling feeling.
