To see mold in your dream indicates that something in your life has been ignored or is no longer of any use. It may also refer to the negative emotions that are expanding and growing in your subconscious. You need to find a productive way to express them before it grows out of control. Alternatively, the mold may also represent transformation. If you dream that you are scrubbing mold, then it means that you need to rid yourself of the negative and pessimistic attitude.
