Some people say that when a person dies, there is nothing. Others say that life is reincarnated, and all living beings will continue their life journey over and over again. Sometimes, when a person is in a certain state, he will suddenly feel a sense of déjà vu, and everything in the past will suddenly emerge in front of his eyes. Some people say this is just an illusion and a dream, while others say it is the reappearance of a distant memory. What about you? Do you believe it or not, people have past lives and present lives?
