I call those thinkos. They're weird to notice. Why did my brain do that? Do I do it often? No idea.

I also find myself making these homophone errors or complete word omissions. It has only started happening since I turned 30. As you say, I seem to have zero awareness of them as they are occurring.

I think it is an advanced state of distraction that causes it, a brain unable to really care about anything until the next dopamine hit.
