Seeing a tannery in your dream symbolizes a place where education and personal growth occur. It can also represent a school or a center for learning, indicating that you are acquiring new skills or working on your mental and spiritual development. This dream suggests that you are striving to gain new experiences or knowledge in your life, which will illuminate your future.
From Imam Muhammad Ibn Seerin's Dictionary of Dreams According to Islamic Inner Traditions â entry "Tannery" (page 429).
A tannery in a dream has the same interpreta tion as that of a slaughterhouse. It also represents a school, a fellowship house, or similar places where the mind and spirit are taught and reared to correct oneself, to hold to what is true and to discard what is false. A tannery in a dream also represents a patient, forbearing and a hard-working woman , ahousekeeper, or a child. Perhaps a tannery in a dream also could denote a harsh, wretched and a contemptible woman, though she likes cleanliness and guards herself from others' impurities. (Also see Dye; Vat)
Note: Islamic dream interpretation depends on the dreamer's circumstances and state. This is a general guide drawn directly from the source book.
