Hi Lava,
Did you know that people talk to themselves 95% of the time. Some people talk in silence while others have outright conversations with themselves. My husband is the later of the two and he is his best listener. Often he is unaware of how much he does it, his thoughts are mostly outloud. Anyone who is around him while he is working, even in his sleep, begins to think that he really is addressing another person.
I have grown to accept this and understand it as he is an adamant problem solver and is thinking about all the different ways of expressing a problem or even an emotion.
I myself often talk thurout a day as I am always thinking and problem solving. It is a way of not only thinking but letting some of your thought and emotions out and using both senses to address the issue. I wonder how many people get pulled over because it may appear that they are talking on a cell phone when they aren't. LOL
When we address another person it is normal for the brain to background think as we are trying to address another person in a way that they will comprehend our message.
When children are small, they almost do it right away as soon as they begin to verbalize and they can even babble out loud at first. I could always tell when my daughter would wake up in her crib as I could hear her discussing or verbalizing about the things that were placed in her crib. As a matter of fact, I had a big teddy bear face at the head of her crib and she would always talk to it, even in a babble when she woke up.
And, that carries on as children grow and seem to have a secret invisible friend, when actually they are doing the same as grownups do in that they feel a need to express their thoughts and try them out in a verbal manner.
Relax, it is a part of being human and having thoughts and trying to express them, not only for others but also for yourself. Did I say what I mean, did it come out right, is there another way I can express it?
I will bet the Benjamin Franklin talked out loud all the time as he was experimenting with ideas. I wonder how many times Thomas Jefferson talked about the ideas that he wanted to end up on a paper as he was trying to write some of the Constitution. And, even more, when the Bible was written, I can imagine how much chatter went into that.
I would not stress about verbalizing and thinking and even questioning at the same time. Most people do it. You are just wondering if you are normal because you are addressing abnormal issues in your past. Even back then your brain was trying to address what was going on. But, really it is just a normal way of processing thoughts and verbalization. There are different ways of expressing issues and the brain can pick one and may be considering others as well. I would not worry about it Lava.
Hope this helps,
