For me there’s two separate participants, a ‘talker’ and a ‘listener’. My mind identifies more with the talker, because that’s the one that has agency. Since there are two participants, both of which are me, I talk in 1st person plural (‘we’ve got to do …’, 'we thought about this earlier’). I stopped being afraid of being alone after I started having an internal dialogue around the age of 11, since having a second participant in the conversation meant I was always in company.
Edit: Wow, looks like there’s a lot more diversity in this than I was expecting


For me it’s like there’s a council in my head, but they’re all me. One takes the center and the rest are all around, in the “room” in my head. Each one is a specialist at a different thing, which includes one of them who is always putting on a performance of a song.
So far I’ve identified:
My wife will poke fun at me because sometimes I’ll end up narrating my own thought processes with “we” and she’s like “Got a mouse in your purse?”
