For me, thinking in words and sentences sounds like thoughs being weighed and slowed down. Seems very unnecessary. On the other hand, I did and always had the the issue of putting my thoughts into words properly. Like the translator is pretty bad and I always struggle and feel like most of the information is lost.
I think there might be some correlation between this and being introverted, socializing is exhausting for me because the translator is not well trained as I don't use it while thinking, and it has to run at 100%. I've talked with my better half about this and she said it's easy for her because the sentences are already there and it takes zero effort to say them, which aligns with my theory.
I do have a terrible "mind chatter" though, I'd rather describe it as white noise. Way too many thoughts going through at once, which makes it very hard to concentrate on anything. So even though not everyone is thinking in words and sentences, this issue can effect all of us.
