Are there really ghosts in the world? Some places are haunted and people are dead?

Yes, this is a true story. My friend's aunt was killed by two ghosts. Their hometown is in rural Shaanxi. It could have been controlled, but she wouldn't listen and then she died. It turned out that the fortune teller told her that she was very dangerous and could be taken as a scapegoat and killed at any time and place. (The day before the date, she was at home with her husband, went back to bed for a nap alone, and two ghosts forced her to drink pesticides. Her husband heard her shout, went in in time to remove pesticides, sent her for gastric lavage and saved her once. Before the date, she couldn't go back to the path her parents had taken. But on the last day, she returned to her family and went that way. It was afternoon 12 when I came back. Everyone felt all right and relaxed. I didn't expect to wake up the next morning and see that she had hanged herself. Did you say evil?
