I study Buddhism, and I often dream about my mother who died more than four years ago. Buddhism

First, she hasn't been reborn yet, and she dreams for you at night when she misses you; Second, the image of your mother is too deep for you, and the subconscious is at work. If she has been reincarnated somewhere, she will not be able to give you dreams. No matter which category you belong to, don't take it to heart, just let nature take its course. Because every old friend's stay or reincarnation is determined by his past karma and present persistence, and no one can change it in any way. Buddha can't change the karma of all beings, let alone us mortals. Besides, no matter where you go, it is an illusion, and the truth will never change. It will not be damaged in hell, nor will it increase in heaven. Heaven and hell are illusions to realize their karma.
