Maybe "you" are the atoms of your body. Consciousness may be just an emergent property of a particular atomic configuration.
Which was why I later pointed out the scientific view of emergentism, to which I was taken to task for talking about a philosophy instead of science (emergentism is a scientific philosophical perspective, just as reductionism is).
Personally, I don't think consciousness is emergent. I think our experience of consciousness, our thinking minds, is where we get confused. We think that consciousness is unique to humans, and call it self-awareness. Rather, I see human consciousness as a particular adaptation of consciousness itself, which is found in all living creatures. That's not to say that a fish 'thinks', in terms of how humans do. But they certainly are aware of themselves and their own environments and make 'decisions' based upon that awareness.
Do rocks and atoms possess consciousness? Not in an easily recognizable way.
Panpsychism teaches that it's consciousness all the way down. I think it was Whitehead who termed it as a "prehension". A way that can be viewed would be that consciousness is the underlying fabric of reality itself, and everything is built upon that and includes it. The experience of any form will depend upon its own biological faculties.
Awareness to a tapeworm, is not the same experience of awareness to a much more sophisticated biological organism like a dog, or a tiger. These are simply the sophistication of the lens through which awareness shines. The human brain, or a dolphin's, or an elephant's brain, is a more sophisticated lens. But the brain does not create consciousness. It simply is a portal to it.
