I dreamed about living in a town. Inside this town, there was a castle and a grassfield. The grassfield was just out of town. The castle was inside town. In the first part of my dream, I was on the grassfield. I was playing along some classmates of mine. After that, we went to town. While going to the castle, we passed a shopping area. There were a couple of annoying kids bugging me there and I was afraid of them. I ran inside a hairdressers place, to hide. The woman there was friendly to me and said I could wait. After a while of waiting, I went to the castle. When going to the castle it was like I was watching the town in it's whole. From the top. I could see a factory and it was polluting the whole town. There was this thick fog all over town. The fog was blue-black. It was scary. Suddenly I was me again, in the castle. I knew the owner was rich, and I was wondering why he lived in such a polluted area when he could easily move with all the money he had.

What does this mean?

A castle can represent your spirt and your natural self. Going to a castle sounds like a metaphor for "finding yourself". A hairdresser is someone who deals with your outward appearance; hiding at a hairdresser's could have to do with being afraid of discovering the truth about something to do with yourself.

I think the man you look at from the castle could be yourself. You are asking yourself why you let yourself remain in a bad situation (the pollution) when you have the ability to change it (the man's money, which doesn't necessarily represent actual money in real life, but just a useful quality, talent, or thing that you possess).
