Dreaming of amethyst means finding satisfaction in careers and relationships. Your levels of expectations are average and you do not necessarily aim for high goals. You are happy earning a living, and living life as it comes. The lack of ambition in you is disheartening. You can do more with your potential.
In a dream, it also signifies divine healing and spiritual renewal.
For example, a man has been drinking too much alcohol and experiencing stress in his life, but he keeps thinking that he can manage the situation by himself. In his dream, instead of the usual alcoholic beverages, he sees himself drinking from an amethyst glass. His interpretation could be that he needs to stop relying on alcohol to feel better and instead turn to spirituality or meditation as his only source of relief from stress.
