Grandma's Life-Saving Prophecy

I have been having the same dream for a whole month. In the dream, my late Grandma looks at me anxiously, repeating the same line over and over: Hide quickly! Only 30 days left! Hide quickly! Only 29 days left! Hide quickly! Only 28 days left! Grandma was a traditional Chinese medicine practitioner who knew some metaphysics. When she was alive, she treated patients and did fortune-telling for others, and most of her predictions were quite accurate.
