Many times. I also sometimes speak out my thoughts, at least when I went to school, I did. I remember one day in class, I was like in my own world and just floated, could not concentrate on my work. Right in front of me was a girl named Liv. I had allways percepted her hair color as black, but now, in my mind, I noticed that in fact it was more like brown, so I spoke out; "hey, Liv's hair is not black, it's brown". Many days before I know that we have discussed some aspects about hair color and eyes, brown or blue..etc. But this remark, just seemed to the others, as it came out of the blue. Very much laughter in class, and me turning red.
Had similar experiences later, but not as distinct. I allways seems to explain me out of the situation.
About your spelling; I do it all the time. The thoughts are faster than my ability on the keyboard. So I often skip or add letters, even in my own language
