Are there real ghosts and fact cases in the world?

I heard it. I really heard it. In 1998, I worked the night shift in the factory and heard three or four women quarreling at three o'clock in the middle of the night. Because my job is to stay in front of the console at any time, press the button every three minutes and count it every ten minutes, so I absolutely guarantee that my brain is awake. There has been no response after hearing someone quarreling, and I have been looking everywhere for a quarrel, but I can't find it. By the time my shift is over at eight o'clock in the morning, I will be the master of the day shift. I should burn some paper or something, because this workshop used to be a pond. Once upon a time, three women accidentally drowned in a pond because of a quarrel. Their generation also heard it, saying that even quarreling and swearing were as good as what they heard. I was so scared that I sweated for three days, and then the old man at home burned the paper for me in July and a half before I got rid of it.
