The head in a dream is one's capital, leader, and manager. A large head indicates honor, high status, and an increase in prestige. The head being cut off indicates freedom from slavery, payment of debt, removal of worry, or gaining great wealth.

The head indicates the father, the manager, or anyone who is a leader. A headache indicates a sin that requires repentance and charity. Whoever sees that he has many heads will have many children, followers, or abundant sustenance.

The head is interpreted as leadership and wealth. Whoever sees his head is cut off and he is carrying it will gain kingship and authority. Whoever eats a human head will gain wealth from a great leader.
