Any existence in an afterlife, is not you. If your soul continues to exist after you die, that is not you, you are not a soul. You have a soul (if souls exist at all), but a part of you existing is not you. When you die, your life ends, and there are other lives lived, but those other lives are not you. Just like the person that was alive before you were born, is not you, the next person that is alive is not you. If you define You as that first person narrative, then there are many afterlives. There are other people that will live after you die, and that is your afterlife.

Why am I me? What does that even mean? Do I mean am I this person or body? How do I know I am this person, just because I experience the consciousness of this person? If I experience the consciousness of someone else, am I that other person and not me? I often wondered if I die, and my organ is transplanted into another person, do I continue life as that person? The idea that I am this person because I can control this body is not possible to confirm. My body moves around, and I just experience it. I am not me, if me is just an avatar or something. I have a body, or am I a body? It seems if I wasn't born, I'll just be somebody else. Am I a person now, but at other times I was and will be somebody or something else? Why am I me? There is one thing, everything. Can I be this everything?
