When people 'die in their sleep' are they actually asleep during the process, or would that process wake most people up?

Obviously, it's not possible to say with certainty what people who die in their sleep experience as they die, but usually these types of deaths are the result of sudden cardiac arrhythmia. Even in people who are totally conscious, the sudden onset of a rhythm disturbance this serious would cause loss of consciousness in only a couple of seconds, since it quickly causes a drop in blood pressure, which means you stop adequately perfusing your brain.
