Nabulsi said that marrow seen in a dream signifies buried things and grain received by inheritance.
Seeing marrow in one's bone signifies wealth that the dreamer will bury; if the dreamer is sick, it signifies recovery and getting back on one's feet.
Ja'far al-Sadiq said that seeing brain and marrow is interpreted in three ways: hidden wealth, sharp and powerful intelligence, and accepted goodness. Breaking another person's bone and sucking out the marrow, or extracting and eating it by some other means, signifies taking that person's property by force.
