What do you daydream in public?

I always daydream wherever and whenever I was. And every day is a whole new story. Well, sometimes I would continue my favorite stories. And some of my daydreams came from my dreams though, and probably some from my own life experiences. It was like a whole library here in my mind! I would constantly write my daydreams into my notes then wait for another daydream. Then my daydreams are often fantasy, action, supernatural and etc. Not horror though, I'm a scaredy cat.
