Two women arguing in a foreign language
Laying in here in bed here on my right side, I'm not falling asleep, and then I suddenly realize that there are these two women in my head, and they're arguing ... it’s a foreign language ... I’m guessing French, though I don't speak French ... one women leaves, and then the other women leaves. Then I realize what just happened in my head, and I think "What the heck was that?", and then someone answers my question, and tells me "They’re arguing over a toothbrush, how ridiculous!"
No telling what your brain will come up with, especially when you're living in a town known for tourists.
