Has anyone else noticed how strange it is to have someone speaking to you fluently in french in a dream if you don't know the language? Or any other time something would seem perfectly normal for another person to know, but then thinking back you realize it all came from your own mind and you don't have the slightest clue... Like things you know, but you know you shouldn't really know, y'know?
I had one where I was chatting with a friend about cars and he was spouting all sorts of technical information about engines. I don't know a thing about engines.
