Is there a current issue with your father? If so, your dream is showing you how you feel about the situation and may even be showing you what you can do.
If there is no issue then your father is not playing himself but instead is standing in for your father-like abilities: your ability to make decisions, to make money and to be assertive. If there is something wrong with your father or if he dies in your dream then ask yourself if you feel you have lost your ability to make money or make a firm decision.
If you are a father yourself, then your dad is standing in for your own role as a father.
