A coworker who speaks nothing but English was staying with some friends who overheard her talking in her sleep. She was speaking German. One of those who overheard her was fluent in German and said that to the best of her understanding the sleep-talker was a Luftwaffe pilot radioing that he was in trouble. Now, that's strange.
Wow. That’s amazing. I’ve been told I talk in my sleep, but no reports of German. But German was one of the languages I spoke. Also spoke Italian, Russian and Japanese. So strange!
