The Cow
Scholars have said that a cow in a dream often symbolizes a year, with its fatness indicating prosperity and its leanness indicating hardship, and its colors and spots reflecting the nature of that year. The cow is also associated with women and family; its refusal to be milked may point to a wife's disobedience, and milking it symbolizes pregnancy or gaining wealth and honor, while its loss or affliction indicates the wife's corruption or a calamity among relatives. Riding it or tying it in the house expresses wealth, joy, and relief from worries, and a small calf may signify a child.
