Does work count?
I spent three months in a coma and although I had a few semi lucid moments, I really wasn't aware of anything going on around me. I came out of it three years ago today
This is something i believe you'll be interested in its sad but something you dont ever see i found it on youtube: http://www.youtube.com/watch?v=JWWHjb7CLgk
Just because a person is "unconscious" this does NOT mean that what is said in the persons vicinity is not recorded in the memory, because it is.
