What does this recurring dream mean?

Over the last few months, I've had a dream I keep having. It starts off by being with a bunch of friends, but for some reason, I become separated from them. As hard as a try, I can't get back to them; every direction I think is right, it takes me further away. Eventually, I end up in a neighbouring town. The dream usually ends with me at least starting on the way home again. One dream, I had a cat with me, but by the time I caught the train, the cat had disappeared. Can anyone tell what this dream means?
