Granite
To dream of granite represents something in your life that is impervious to any type of influence. Something about yourself that you notice never goes away. A mindset or situation that you feel is impossible to change.
Example: A woman once dreamed of having a sliver of granite removed from her heart. In real life she was learning to get over bitter painful memories from a past relationship after meeting someone new. The granite sliver reflected the pain from her breakup that made her feel a new relationship would never be as good.
