have you ever written a word, spelled it properly, and then decided you got it wrong

Absolutely! What's even weirder is when you look at a word so much that it loses its place in your brain. Once in 8th grade I remember a form we had to fill out with our self-selected spelling/vocabulary words. It was just a bunch of lines, every other one a short one starting with the word "word".

I looked at that paper until the word "word" lost all recognition value. Usually when you see a word something in your brain goes "hey, I've seen that word before!" You don't realize it's happening until it stops happening. I looked at the word "word" and for the life of me couldn't remember ever having seen it before! Verrrrry strange feeling!
