I wondered about this at one point. I'd been under full propofol sleep a couple of times due to knee operations, and the experience was quite interesting.
You fall out of consciousness insanely fast. One moment you're talking to the anaesthetist about your name, what you're there for. You feel a cool sensation where the needle is. Before it's grown to your whole arm, you've vanished. I mean you're not dreaming, you're gone.
The only way you know you were gone is that there's no sensation of time. When you sleep, you feel like there's time. Under propofol I felt like my arm was cold, then I was groggy and waking up. In one action.
Maybe it's like dying, I don't know. But there's definitely this "system was rebooted" sensation as you come back to consciousness.
