I hope this is false in my shallow consciousness. My grandmother didn't die. I dreamt that my grandmother died at first sight. You didn't fully fulfill your filial piety before she died. So, I feel sorry for my grandmother. In my dream, I feel that my grandmother will be angry, teased and retaliated. So in my dream, I was afraid of everything she came back to life. This dream is just a reflection of your heart and subconscious. If you feel uncomfortable or uncomfortable, it is recommended to cross over the dead within 49 days, release, seal, give alms, vegetarian food, etc. For her, this is not only beneficial to the deceased, but also beneficial to all relatives.
