Yh I think that is big possibility, much more likely then this reality being the one true reality. But if we can reincarnate it is very likely that we will not remember anything and will not know about any previous lives, as this will defeat the point of existence we exists through different bodies forms so we can improve our souls. Well that my interpretation of that, and that's why I am a vegan because during one life time I may reincarnate into a cow and I would never want to be treated how they are in the animal agriculture industry.
