Family member talks to themselves.

I’m not sure how to approach this family member to discuss the behaviors I have observed. I know their medical history does not have any type of mental health diagnosis.

They talk to themselves. A lot. Not when they are immediately around other people, but when they are by themselves even if other people are in the same house. They don’t talk harmful things, but they go up and down in their intensity with the conversation. It seems like there are different “roles” by the way conversations go. One is angry, one is sad, one is logical, one is encouraging. The person doesn’t use different voices, but there’s a pattern to the conversation.

What do I do? What can I look up to learn about before I approach them? They are healthy, late 30’s, educated, and successfully living on their own. They don’t have kids or a spouse though. I’m not scared OF them, I’m scared FOR them. Again, it’s not harmful talk. They just sorta don’t like themselves and the common ending is “frick it, you’ll be fine even if no one gives a shite. Show them how fine you will be by doing what they said you couldn’t.”
