Your dreams are a reflection of the beliefs stored in your subconscious mind. Your dreams will tell you what your current beliefs are. So if you don't like you dreams, this only means that you need to replace your existing beliefs with new ones.

You can do this by focusing on your desire more frequently through visualization. With repetition, your subconscious will eventually accept what you consistently focus on as a new belief. Your dreams will eventually reflect your desire. 

Take your dreams as signs of whether you are on the right or wrong track in relation to your desire.
