After my mother died, my sister often had that kind of nightmare, which was very sad. All kinds of scenes show that my mother is in a very difficult situation. Then, I asked my sister to read Amitabha for a period of time every day when she was free. After reading it, I made a wish that Amitabha would help my mother. Before long, my sister stopped having nightmares. Finally, my mother told her in her dream that she was fine now, so that my sister should not be sad. This is my sister's personal experience, that is, reading Amitabha can help people who have passed away, no matter where she is.
