(Feeding trough) Seeing a manger or a feeding trough in a dream means having power, receiving a gift, or it could represent one’s intelligence, diversification and qualifications.
A manger in a dream also represents a woman. Seeing two animals feeding from a trough in a dream means that one’s wife is hiding a secret affair.
