A girl is climbing a mountain, all by herself, bundled up but short on climbing gear; if she falls she'll hit the ground.

"I'm gonna converge here now." Nothing observably happens. "See, my power's this -" Then there's two of her. Then there's one again.
Does your soul split also, or is it just controlling two bodies at once? Like, one way you might be able to tell is, do you have one stream of thoughts, or two which get reconciled later?
"...did I say we did that? I am like ninety percent sure I didn't say we did that on account of we do not."
That's awful.
Uh, so usually I'd explain souls by saying they're the part of you that survives the destruction of your body but if you can't talk to those then that won't be helpful. So - they're the part of you which has memories and thoughts and experiences. You are a soul, you inhabit a body. That sort of thing.
...I suppose that is possible but since souls are the thing that does thoughts and experiences, and you have those, it seems likelier you have them but the difference isn't relevant when you can't resurrect your dead.
