Islamic Interpretation of Dreams (Ibn-i Sirin):
(Abscess; Boil; Postulate; Pus; Swelling; Tumor; Ulcer) When one sees that he has contracted pimples that open, and ifpus starts running from them in the dream, it means benefits or a booty.
In general, open wounds and pimples in a dream represent money and profits, unless ifthey appear in high concentration or cause sufferings in the dream.
Thus, pimples could represent money that keeps coming as long as the pus has not dried in the dream.
(Also see Swelling)
