Islamic Interpretation of Dreams (Ibn-i Sirin):
(The color red; Dignity; Nobility; Happiness) Wearing a red silken garment in a dream means a sickness.
If a warrior sees himself wearing a red silken garment in a dream, it means that he will be decorated for his chivalry. Red in a dream also represents the world, its glitters and material pleasure.
