Conscious versions of each other
From Aware Theory
Conscious versions of each other means that they are consciously as much like each other as are the compassion of different sections on your life time are to each other (assuming that you actually experience these different sections of your life time). For example, how close is your curent consciousness to your consciousness that you experienced a year ago? Did you experience both of them? If you did then this is how close conscious versions of each other are consciously to each other.
