Kind of.
Our minds possess the power of creation. On the stage of our thoughts, any scene can be set, any characters cast within, any dialogue, any plot. These imagined persons have a bit of the essence of the real person they’re based on. They might even be combinations of different persons.
This ability of ours is curtailed here in the physical world because our minds are disconnected for the most part from the broader spiritual world. But once separated from our physical bodies through death, some people have experienced this through the near-death experience, we can access the boundless world of connection, where time and space are mere suggestions.
In the spiritual world, it’s essence that matters, not form or continuity. Our minds continue on into what we here call the afterlife, but our essence, just like the essence of a flower, can be recreated, entirely, say by growing another flower, and can also be mixed and altered to fit other conceptions, like an actor putting on a new suit and taking on a new role.
There is a real world we inhabit when we die, very much like the physical one, with different rules, but no less ‘real’. There is also the world of imagination, which remains unchanged. We possess the same minds in the afterlife as we do here. It’s just that we can create more interesting and vibrant things in our minds, and those creations can affect the ‘real’ world in a greater fashion than our imaginations can create things in this world.
If I want to create a dramatic scene in this world, I need to find actors, write a script, devise props, find a stage. It’s a big production, and a lot of work. In the spiritual world, I can just think it into existence, and anyone interested can find whatever place they want in it, including playing as one of the characters or just riding in their ‘body’ as someone else plays the character. There just aren’t any limits to what anyone wants to do, because if someone wants to go do it differently, they can simply think a different version into existence.
Lack of time and space restrictions means you can be everywhere, and nowhere, the only limit is your ability to perceive and respond. God is still omnipotent in the spiritual world, with the ability to perceive and respond anywhere and everywhere at once. But we are still limited in what our minds can do. Through the other spiritual ability of surrender, we can continue as individuals rather than have our agency slowly fall apart as the endless splendor and wonders eat away at our sense of self.
People who have to have it all their way, all the time, who cannot surrender, tend to fall apart quicker in the afterlife, and have to get reborn many many times into concrete worlds like this one in order to learn spiritual lessons. Those whose wisdom allows them to find spiritual surrender early in life have less dividing them between their former lifetimes.
Every human already has millions of years of spiritual evolution behind them. To find out what humans looked like before they were human, look at the process of biological evolution. Animals have minds and spiritual journeys just as we do, those journeys are just not quite as complicated.
So yes, millions of versions of us exist in the spiritual world, and they’ll all come back and join us once we cast off our mortal coil.
