In a dream it is a sign of poverty, weakness of condition and decline in standing. If the emaciated one is a king, it indicates a barren year, high prices in his land and the weakness of his troops. It is said emaciation is illness; it is said it is hunger; and emaciation may come from passionate love and grief.
