A dream of finding money suggests that the dreamer is becoming aware of their intrinsic value to themselves and others, from a spiritual, rather than a material perspective. It can also indicate a recent success or imminent achievement in their waking life in which their self worth is visibly manifested.
Often this dream indicates that the dreamer possesses special artistic or creative abilities that they are in the process of becoming aware of. Sometimes the dreamer feels guilty when they find the money which may indicate that their self esteem is currently lower than normal, and they should value themselves more than they currently do.
You are worth more than you think you are, and should not feel reticent about taking the chance to prove your value to yourself and others. As you become more aware of your own self worth, you will become more confident at exploring opportunities in your waking life that are to your advantage.
