Islamic Interpretation of Dreams (Ibn-i Sirin):
(Decoration) In a dream, ornaments are a sign of poverty.
If one sees the world decorated for him and he is able to ask for whatever he wishes from it in a dream, it means that he will become poor, or that he may face destruction.
As for unusual ornaments that are not recognizable, or decorated lands one does not recognize, then ornaments are a good sign, and the same goes for wearing customary or traditional ornaments one is used to adorn himself with.
