Islamic Interpretation of Dreams (Ibn-i Sirin):

(Cerebrum) In a dream, a brain represents savings. Having an oversized brain in a dream means reason. Having no brain in a dream means ignorance. Eatingfrom ones own brain or the marrows ofones own bones in a dream means suspicious dealing with ones own money. Eating someone elses brain in a dream means that one may die shortly or that he may steal someones savings.

A brain in a dream also may indicate ones beliefs, religious life and the work of ones innermost being.
