I've hypothesized that in a simulation, "others" in your world may just be permutations of "you" in some sense. That everyone you interact with is actually a creation spawned by "your" entity. It's one of the reasons dogs and owners frequently look alike -- because their origin is from the same logic, and that connectivity yields inherent similarities for entities created to have some degree of symbiosis.

It's crazy -- and certainly wrong. But so is all of this.
