What does this dream mean?

It’s a dream about me (a girl) and two of my friends (boys), we were suddenly transported to a world called “The World Of Dreams”. So we walked through that world and whenever we meet someone in need, we help him until some people caught us because we were strangers to them. These people wanted to slaughter one of us, and throw another off a cliff in order for him to fly. Anyway before anything happens, the people we helped before came to help us, then we were freed. We continued walking and found another man who needs help so we helped him. By coincidence this man happened to be the King so, in compensation, he hired us three to be his assistants.
We went to his palace and we were given the right to use anything in the palace ( wear all kinds of clothes, all kinds of accessories, etc).
Suddenly, the king disappeared and the palace was surrounded by police from our world, when we got out we found ourselves back on Earth. We ran away from the police and that’s all.
Can you please tell me what does that mean?
