(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. Eating from one’s own brain or the marrows of one’s own bones in a dream means suspicious dealing with one’s own money. Eating someone else’s brain in a dream means that one may die shortly or that he may steal someone’s savings. A brain in a dream also may indicate one’s beliefs, religious life and the work of one’s innermost being. (Also see Body’ | Marrow)
