Dreaming about a city means the psychological condition of being lonely, which may be due to the person’s sense of self-isolation in everyday life or an inability to socialize with others.
Same as how confusing a city could be, there is no definite interpretation for a city in a dream. The meaning of the city depends on the context and feelings that you associate with it. For example, if you are running away from someone and you see yourself running through the city, then it could represent how you feel overwhelmed by all that needs to be done.
However, if you see yourself living in a beautiful city with everything at your fingertips, then this may show that you are not appreciating your current situation or there is something missing from your life.
Lastly, a dream about a city can be about where we feel we belong or about our future plans. It can also take place in a symbolic way like being lost in an unfamiliar location or being pursued by danger.
