What does it mean if someone does not have an internal monologue?

Hey guys, long time no talk! Hopefully you’ve all been good.

Anyway. I have a friend that I was talking to the other day, and he told me that he doesn’t “think”. He explained it as just “accepting” what happened and not feeling an emotion to go along with it. For example, he didn’t get into a Psychology program at his school, but he wasn’t sad or upset – he just accepted it.

To go with all of this, he also told me that his mind is just blank. He doesn’t think in his head like most of us do, I don’t believe. When he talks, he just talks. He doesn’t think to himself. So when I wake up in the morning, I think “Oh, I don’t want to get out of bed. I’ll have to move the cat, and the floor is cold, good grief.”

Is there a meaning when someone doesn’t have an internal monologue or just doesn’t think? I know this is a vague question, but I’m curious. I tried to research it but it just gave me stuff about schizophrenia.
