Hey Wandering Soul
I do talk out loud. It's a way of fighting loneliness. And the scenarios thing, I know this as well. I'll daydream and get so involved with my imagination (and imaginary interlocutors) that I start to talk out loud and wave about and stuff. There's a term for this actually, it's called "Maladaptive Daydreaming" (sry I know you're not into the labeling thing) . The name sounds negative I don't see it that way though. If you're that socially isolated it would practically make you go insane, daydreaming helps to survive. -/-
