I talk to myself constantly. Actually, I sit with my emotions, each of which have a persona, and we chat, sometimes for hours. Countless times my wife has walked into my space and asked, "who are/were you talking to?" I always reply, "me." She always says, "oh, okay."
Other times I'll say sentences or impromptu fictionalized speeches out loud to hear the sounds or to practice delivery of certain tones. Sometimes I'll just sing or talk or make noise.
Ironically, none of this and none of the internal dialogue is what keeps me from sleeping since I externalize all of it. I don't think I'm insane or bonkers but would I really know otherwise?
I really enjoyed this article and your perspective on it. It's comforting to know how others handle moments like these and how these voices affect each of us. Great read!
