Hi everyone I'm new to the forum but have been lucid dreaming for 3 months now. I've had about 6 lucid dreams but only 2 fully lucid. Anyway I have a problem.

I've only encountered DCs once so far, and they couldn't understand me. I only speak English, so I went up to a group of DCs who were talking. I said "Hello, I'm dreaming!" And they just looked at me. I said hello again. Then one dc turned to the other and they started speaking in German, and then they all laughed. Then one said in a very thick German accent "stupid American, we not speak English". So I left and encountered more DCS walking and noticed that all of them were talking in German. I don't know german, and have never heard much of it. Plus this dream took place in somewhere resembling where I live. Does anyone know why this happens?
