Nearly always when people dream about someone they know they automatically believe the dream is about that person. But when we think of our friend or partner our thoughts are not them – just our thoughts and feelings about them. In the world of dreams our most intimate fears and longings are given an exterior life of their own in the form of the people, objects and places of our dream.
So to some extent an uncle or uncle is a role model in our dreams. We gather from their success or failure strategies for our own life. Whatever feelings we have about them, whatever we think of them, the dream will use this to illustrate something for you. So consider how you would describe your uncle, what sort of person he is, and how you feel about him. The dream will be using his image to illustrate the role you see him in. If he is a success, ask yourself what in yourself you are facing regarding success. If you feel he is a failure, ask yourself what of your own feelings about failure you are facing.
Most adult figures would suggest either a parent or authority figure as possible role models; or a target for admiration or sexual attraction, perhaps even because of some form of security in love and being cared for.
Athletes, film stars, teachers, a great leader, a person who you admire, the number is endless. As a youth I read stories about Tarzan and Wilson, a sort of Tibetan yogi and they became role models for me.
Such a person can have tremendous influence on the way you choose to live your life, the actions and ambitions you have, and the general quality and mood of your life. The imagination is a tremendous force and is a great power of your creativity. See Characters and People in Dreams - Being the Person or Thing - Hero Heroine
