Interpretation of the Dream
Seeing a moldy wall in a dream indicates that a result cannot be achieved despite a lot of effort and patience in the work to be done for a reason and the efforts and money given will be in vain, that you are in a good mood, that God will be on your side, that you will get into trouble, that you will contact institutions that can help, that sick people will recover and regain their old strength, and that you will be calm spiritually.
Also seeing a moldy wall in a dream indicates that you will make more efforts to do much better, that you will not see any illness for a long time, that you will enter a period of abundance and prosperity, that you will have very difficult times, that you will leave them behind, that you will not be able to get rid of problems and troubles despite making a lot of effort, and that after experiencing great sadness and suffering a lot of troubles, you will slowly recover in your work and continue to earn money.
