As someone who has some oddities around sleep and consciousness (sleep paralysis, lucid dreaming, self-awareness during the process of falling asleep, and a couple of other similar experiences that are extremely difficult to describe), which I suspect may caused by undiagnosed narcolepsy, it is clear to me that sleep is a much more complex process than that and does not necessarily involve loss of consciousness. Indeed, even people with normal, healthy sleep patterns still dream during the REM portion of sleep, even if they do not remember it later. Consciousness is not an on/off thing.
