Have you ever had a repeating dream theme?

I frequently dream of being in a city that's so familiar and so real. And there's always a fountain in the middle of a small square at the corners of four skyscrapers that I'll come to and in the dream I'll realize I've been here in other dreams. The theme is always different, but the city remains the same. Like last night I was being hunted by Russian agents. A few days ago I was testing autonomous cars for Uber in the same city. And last week I was a police officer helping to fight off an alien invasion. Always in the same city though, and always the same fountain reminds me it's a dream. I can't seem to control the dream, but once I see the fountain I know every street, alley and building and exactly how to use the city to my advantage.
