Dream interpreters/people who can read dreams?

I have a dog that is exceptionally well trained, everyone says that, and i agree that he is a very good dog. I hardly had to put any effort into it, he does what he is told, when he is told. But the thing is, whenever i dream about him, he is the most ill-mannered, unresponsive and untrained dog ever, can anyone tell me why he is like that in my dreams?
