Have you ever had a dream where you can't understand how to speak anymore? Your brain works fine and you're having a nice normal chat with someone, and then when you open your mouth the sounds that come out are in some other language, some dead and ancient tongue that no one can understands? Even you can't understand what your words mean, and you don't know where you learned those sounds from. You are hearing yourself speak but your ears can't translate what your mouth has said aloud. And the people around you go white and wide-eyed with shock; you feel frightened by your unreadable babbling but they are aghast at it, your gibberish sounding to them like archane, screaming obscenities. And you flee before they can stone you for your words, your horrible sharp words that are rake like shards of broken glass upon their minds; you flee.
