Receiving something from the dead in a dream is goodness and sustenance. Whoever sees a dead person give him something of worldly possessions will receive good from an unexpected source. The best gifts are those loved in wakefulness.

Receiving from the dead indicates benefit and sustenance. If they give food, it is lawful sustenance.
