Islamic Interpretation of Dreams (Ibn-i Sirin):
Seeing plaster in any form in oneâs dream means preserving oneâs dignity, holding to oneâs status and position, or it could mean persevering in oneâs goals. Plaster in a dream also could be interpreted as having a good marriage, good children, assiduity, concern for oneâs religious duties, applying knowledge to oneâs words, ability to appreciate and to express oneâs gratitude, recovering from an illness, buying new clothing, or drafting a just agreement. Gypsum in a dream has the same interpretation.
Ifa renunciate or a pious person sees plaster or gypsum in his dream, it becomes a proof of an unlawful or sullied substances mixing with their earnings, or it could mean engaging in religious innovations, neglecting to follow the prophetic example, or becoming a hypocrite.
