multiverse as social-psychology

[lemur]

I don't really know much about the concept of "multiverse," but it occurred to me that this term could be used to refer to the experience of meeting other people that exhibit various degrees of identifiable resemblance to oneself and ones own experiences. So, for example, you may have begun with pre-med in your early university years and switched to chemistry. Then, you might run into a doctor later on in life who shares other aspects of your pre-chemistry history. I.e. It could be as if you were running into a version of yourself that you branched off from in choosing to shift from pre-med to chemistry. 1) Does this at all resemble the concept of a "multiverse?" 2) Could people social-psychologically identify with others as versions of themselves that variously diverged and converged in different ways during their personal development processes? I.e. are people living in a multiverse of potential versions of themselves, subjectively, as a result of interpreting others in terms of recognizable aspects of their own lives and knowledge/culture?
