So we have the same Hashkafos and passions etc?
Unlikely. You’d be the product of two very different times and cultures, shaped by very different experiences.
Think of it this way… perhaps your neshama is like a specialized type of clay. An experience potter can make many different things with it, depending on the types of pressures, heats and other factors applied to it.
Your neshama could turn out a million different ways, based on where you live, when you live, who your friends are, the time and culture in which you live and on and on. If you met an alternate version of yourself from a universe where things worked out very differently, you might physially be the same people (like a set of identical twins), but emotionally, spiritually, culturally and mentally, you’d be very different.
Likewise, the “you” from a five hundred years ago in Europe, and the “you” who lived a millenium ago in Spain and the “you” who lived two millenia ago in present-day Iraq are all very different people. The factors that form your neshama, like those that affect the clay, are very different in different circumstances and, as a result, the final form will be very, very different.
