"To see or win money in your dream indicates that success and prosperity is within your reach. Money represents confidence, self-worth, success, or values. You have much belief in yourself. Alternatively, dreaming about money refers to your attitudes about love and matters of the heart. It is a common symbol for sexuality and power. In particular, finding money indicates your quest for love or for power."
" If you dream of a person who has died a long time ago, then it suggests that a current situation or relationship in your life resembles the quality of that deceased person. The dream may depict how you need to let this situation or relationship die and end it. If you dream of someone who has recently passed away, then it means that their death is still freshly in your mind. You are still trying to grasp the notion that he or she is really gone. If the dead is trying to get you to go somewhere with him or her, then it signifies that you are trying to understand their death. You also don't want to be alone."
I didn't write any of that but hopefully it can help.
