It's a very interesting question. I think it's pretty straight-forward that 'ourselves' is a composite of 'awarenesses' with non-overlapping mutual awareness.

Some data with respect to inebriation:

• drunk people would pass a Turing test, but the next morning when events are recalled, it feels like someone else' experiences. But then when drunk again, the experiences again feel immediate.

• when I lived in France, most of my socialization time was spent inebriated. For years thereafter, whenever I was intoxicated, I felt like it was more natural to speak in French than English. Even now, my French vocabulary is accessible after a glass of wine.
