An inner monologue. I talk with me it helps to think while I animate and do the voices. Got to talk to someone though in average I am a quiet person (headsets, sleeping through the day and I work at night). No demons here. Automatic writing makes everything easier you should ask my mom. She types and talks at the same time about a different topic to whoever needs attention. Kind of weird but works for her. I escape the conversations. I am not sure if I use a prompt. I'm ll give it a try and will write the result underneath.
Does your mom write for a living? I'm not above reading stuff outloud, but I definitely wouldn't be able to hold an unrelated conversation. That's next level.
