It may already be here. Ten years ago I went into the hospital to have a stent put in a heart artery. I was awake the entire time and watched the procedure on a TV in there.
After it was done, they said I did well and was asleep during the operation and snoring like a baby. When I said I was awake the entire time they informed me they had given me an amnesia drug to forget.
So was I awake or asleep?
