To dream that something is decreasing could indicate that you fear you lack something. Examine what is decreasing in the dream to gain an understanding of what you feel you are lacking. For example, if you dream that a pile of money is decreasing, it could indicate that you are afraid you will lose money or a feel a general lack of financial abundance in your life. Alternatively, this symbol could represent a feeling that some part of yourself is diminishing or no longer holds as much importance as it once did.
