Objectively self-awareness is just inner-awareness vs outer-awareness - what you might consider as another sense, but where the sensory inputs are parts of the brain rather than external (eye, ear, etc). So, the watcher and the watched are both the same - the brain. The "self" is just a psychological construct - the actor behind our actions, which in fact is just the brain. This is just the way our brain has evolved to understand/predict an evolutionary landscape full of autonomous agents, who we need to model to predict their behavior. There's no fundamental difference between "self" (my-self) and "you" (your-self) - our brain observes some (inner or outer) entity as a causal entity, and models it.
