I don't really talk to myself out loud, probably because at this point in my life I am very rarely at home by myself, but whenever I am alone in a room or something like that, I find myself kind of silently mouthing the words of a conversation with myself. Usually there are like two "voices" talking to each other about whatever I'm thinking about, so it's more of an internal dialogue than an internal monologue. It's a weird but I guess pretty effective way to think things through. Often I don't even realize I'm doing it, it's sort of instinctual. After typing this out I realize how weird that sounds. I wonder if this is a thing that many other people do
