I am not sure my post is appropriate for this forum. Since maybe 6 months ago I've been experiencing a mild "disconnect" between what I am typing and what I am thinking. In general I type quickly without looking at the keyboard. I started noticing that some sentences come out differently then what I was thinking. Sometimes I change a word from singular to plural, or change completely the verb tenses, or even rearrange words in the whole sentence. It happens maybe once or twice per day and I need to re-read everything I write.

English is not my native language, but this happens also in my native language.
Does anyone have an idea what this might be?
