Everything I read about it says there just has to be an alternate universe where your mind exists, is that the idea? Forgive me I'm an idiot.

The simplest explanation imo is to work backwards: some jerks a long time ago believed in souls and wanted to rationalize how this could be, given that bodies are clearly material and and you can sense things with them and send instructions to your body. The natural conclusion from people that really want to believe in souls is that your soul is basically sitting in a little cockpit somewhere, impervious to the material world but still able to interact with it via whatever series of logic ensures that you don't have to think too much about it.
Then add centuries of philosophical window dressing.
soul is literally psyche in ancient greek, so it isn't so much that people try to rationalize souls but that the concept of soul/mind/psyche coincide/overlap from the beginning, now you can go the analytical route and say that it is all just semantic confusion and that we should do hard categories but i think the contrary is better, soul evolved as the mind/psyche specialized to a religious context, recentering it makes it lose its specialness, there is no such thing as the invented (one might say god given) concept of soul; if there is something special to the mind, following this enlarged concept it is (your) uniqueness as tracked by (your) soul (essence)/mind (consciousness)/psyche (yourself as shaped by material conditions)
