I dreamed that I was walking on the road with some people I didn't know, similar to the scene of a village in the city, with tall buildings beside me. Where have we gone?

So there's no need to watch too much. Be sure to relax yourself and strengthen physical exercise. This is good for you.

Your dream has no special meaning at all. Generally speaking, if you dream that a building or house falls down, your family or relatives may get sick. I suggest you pay more attention and care.
