From a psychology perspective each dream and everything in the dream is about you. It is a message about you, something that you already know deep inside, but not on a conscious level yet. Dream symbols can represent aspects of what you are feeling about your life. For example, if your dream is about riding in your car with someone else driving, it can mean that you feel like you do not have control of your life or that you have given control over to another person. Analyzing dreams can be helpful for understanding what is buried within, and it can be the basis of healing sessions or useful information as to what needs to be healed in the subconscious.
When healing, and at all times of your life, it is possible to receive helpful information in your dreams. Trust it. Use it.
