Or when you spell a word and there's no red squiggly line to say it's spelled wrong but you swear that's not how it's supposed to look. Then add random letters to the end to test if the spellcheck is working and it confirms you spelled it right the first time.

Yesterday I was trying to write out ‘inconspicuous’ and my brain short circuited. Could not remember what word I was trying to spell, how to say it, I couldn’t conjure it on the white board in my head. It was like it was suddenly purged from my memory.
