Seeing a ewe in your dream generally symbolizes a woman or a wife. If you find yourself running after the ewe and failing to catch it, this indicates that you are attracted to a woman but are unable to influence her. This may reflect some difficulties or challenges in your relationships. Additionally, the ewe often represents prosperity and success.
From Imam Muhammad Ibn Seerin's Dictionary of Dreams According to Islamic Inner Traditions â entry "Ewe" (page 145).
In a dream, a ewe represents a woman, a wife or prosperity. Running after a ewe and finding oneself unable to keep-up or to catch it in a dream means chasing a woman and failing to seduce her. Milking a ewe in a dream means good profits for that year. Eating the meat of a ewe in a dream means inheriting a rich woman. If a ewe leaves one's house in a dream, it means divorce or the death of one's wife. If a ewe turns into a ram in a dream, it means infertility. A pregnant ewe in a dream means expecting to receive some money. Fighting with a ewe in a dream means an argument with a woman. Seeing a ewe in a dream also means distress, adversities, loss of one's husband or job. (Also see Ram; Sheep)
