Sheep's Milk
Scholars have said that whoever sees themselves eating sheep's milk, it may indicate a long life and that they will acquire good fortune beyond their hopes or greatest wishes. The interpretation is similar for eating the head of a cow, ox, or human, with some being superior to others, as the human head is considered best in worldly affairs.
