What is consciousness? Where does it go when we sleep? When we dream? Does consciousness need external stimuli—light, matter, a world—to be conscious of? Neuroscientist and sleep expert Giulio Tononi sheds light on these difficult questions.

General anesthesia was indeed a shocker.  No sense of time passage, but the time is gone and you have nothing.  One moment you close your eyes, and when you open them again, many hours are gone; just gone.  Freaked me out.  Even dreamless sleep has a feeling that you have been "out".  Anesthesia is a pure leap forward in time.  Brrr.  Gives me the willies just thinking about it.
