Mixing plaster in a dream forecasts a period of money luck; putting plaster on a wall is an omen of increasing prosperity; however, cracked or falling plaster portends family troubles. If you dreamed of wearing a medical plaster or a plaster cast, you are likely to have to defend your reputation as a result of your own careless behavior, but if the plaster was on someone else, you are likely to be called on to help a friend or relative who is in trouble.
