In the city gate cave, there are alleys with twists and turns. People are always chasing me, and I hide in a house (weird child). There is an oil painting board in the room.

I don’t really understand it, but using Freud’s method of guessing, I think it’s because you have some kind of fear in your current life, or maybe it’s some kind of shadow from your childhood. You keep running away but have some doubts about your chosen "refuge". That weird kid could be your childhood self. The child and the canvas may symbolize the reasons why you have doubts about your "sanctuary."
