Islamic Interpretation of Dreams (Ibn-i Sirin):

(Constrains; Modesty; Reserve) In a dream, bashfulness means an excuse.

If a bearded person sees himself bashful in a dream, it means that he might suffer imprisonment. Bashfulness in a dream also could represent a myrtle, or any aromatic plant. Bashfulness in a dream also purport a clear excuse, increase in one’s income, the arrival of a traveller, or receiving a letter from him.lfbeing bashful beautifies the person in the dream, then it means glad tidings. Otherwise, if one feels ashamed from it, then it means distress and adversities.
