Dyeing with Clay or Plaster
Scholars have said that whoever dreams of dyeing their hair with clay or plaster is seeking an impossible matter, and their affair will become public. As for a woman's beard in a dream, it may indicate that she will never bear children, or it points to her illness. It was also said to signify an increase in her husband's and son's wealth, and the honor of her child, or the absence of her husband if she is married. If a pregnant woman sees this, she will give birth to a son whose affairs will be completed.
