I type words in my mind?

When I was younger I had a bit of OCD. I would often touch things four times or more, and if I didn't, this voice in my head would urge me to until I did what it wanted. I also had to balance things on my sides and make sure everything was even. If it wasn't, I kind of just curled up in my own little world and tried not to think about it. I think I no longer have it (when I think about it however it makes me want to), but ever since I could remember I have typed words in my head. I'd have a mental keyboard and mental hands typing out words I hear or see in real life. To make it even worse my mental fingers write down the letter on that specific spot of the keyboard where it is. This doesn't make me any slow of a reader or writer, though. I know this has already been asked but I do it a bit differently (the writing it down part).
