Modern dream interpretation subdivides the image of dreams, and holds that dreaming of mummies represents rigidity, inflexibility and lifelessness. It means that at present you are bored with your environment or what you are doing, and when you face it, you feel a little scared. I am eager to change this situation, but I have no clear goal on how to change it, so I just feel depressed.
Moving the mummy's skull in a dream and splitting it in half symbolizes that your situation will change. Although it may not completely change the status quo, it will make you feel better. For example, promotion, change of environment, etc.
At the same time, this dream may also symbolize dissatisfaction with one's current ability or physical condition, such as being inactive in thought, inflexible in limbs, or feeling without passion. According to the Book of Changes, your kidney qi is a little insufficient at present.
If this is the case, you need to stop your current study or work and have a rest in a different environment, which is of great benefit to you.
