Ibn Seerin Interpretation:
In a dream, seeing a mountain or an edifice or a mausoleum breaking into pieces or being destroyed without an outside interference or blasting, it means fading of one’s name or evanescence of one’s remembrance after his death or disappearance of one’s traces or references. Crumbling in a dream also means fulfilling one’s promise.
Realization that I can use my inner strength and confidence to support me rather than continuing to let things fall apart
