Several years ago, I had knee surgery. My experience with anesthesia was total oblivion: no consciousness at all, completely and utterly absent of mind, no sense of even blackness, just nothing at all. You may think you are unconscious when sleeping and not dreaming, but this was somehow even more "gone" than that. This is how I imagined death must be. When I came to, I awoke with my eyes closed and pretended not to hear the nurses talking until I decided to speak finally. I had no memory loss of events afterwards; although they didn't seem as clear.
This past Friday, I finally got my wisdom teeth removed. I was given a general anesthetic intravenously combined with laughing gas. This experience was totally different from the first. I slowly became more light headed and tingly (and slightly claustrophobic) until I was semi-consciously seeing a blurry orange-ish beige color. I had the feeling of looking at this colorful blur over the edge or horizon of something (probably the laughing gas nose mask). This was more akin to a dream. I was completely unaware of my surroundings, and I was not having any thoughts, but I was conscious and seeing something. I don't really recall the moment of coming to however. My wife took video, and upon seeing the video I remembered everything we'd talked about immediately afterwards and during the drive home, but I probably wouldn't have remembered much without talking to her or seeing the video. The car ride home was much longer than I remembered, so I must have slept for part of it.
Anyway, I thought it was interesting that my two experiences with anesthesia differed so greatly, from "I know what death feels like and this proves there is no soul" to "I was half asleep looking at a color."
What have your experiences with anesthesia been like?
