I was once told that the actual content of a dream is insignificant as compared to the emotion it creates within you. I have found this to be true for myself. If my dream is beautiful, I am generally feeling good about life. If my dream leaves me waking up scared, there is something in my life causing fear. And if I wake up feeling anxious or stressed, you can bet I have something anxiety producing going on in my life.
So it appears, at least in some cases, that your subconscious is trying to tell you the state of your emotional well-being.
