The Big Dictionary of Dreams

by Martha Clarke
They not only represent an excess of attributes but also— proportionally—taking care of your own image or home. You must pay close attention to the context of the dream because it can be indicative of either vanity or nobility, as well as austerity or loss.

My Dream Interpretation

To see or hang an ornament in your dream, represents the things in your life and the things you do to make you feel good about yourself.

It is also symbolic of a spiritual gift.

Islamic Dream Interpretation

by Ibn Seerin
(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.
