[Ling Feng] A simple yet twisted reasoning problem, sleazy

① There was a young man whose house was separated from the neighboring couple's house by a lawn. One night, the man was awakened by the noise of the neighbors arguing. Afterwards, he heard sounds of things being thrown, a knife being chopped, and a cow grazing. After a while, he also heard someone knocking on his door, but he ignored it and went back to sleep. The next day, he found the neighboring husband had been brutally killed at his doorstep. Deduce the process. ② On a sunny day, a man was reading a newspaper under a very tall building. After reading a piece of news, he suddenly ran to the top floor of the building, turned on the light, and jumped off to commit suicide. Why? ③ On a rainy night, a man was in a car listening to the radio. Then, suddenly there was a flash of lightning, followed by thunder. Due to interference from the lightning, the radio stopped for a few seconds, and then the man committed suicide. Why? ④ Once upon a time, there was a beautiful princess under a wizard's spell, locked in a castle and in an eternal sleep. It was said that only a prince's deep, heartfelt kiss could awaken her. Later, a very handsome prince captured the castle and rescued the princess. However, after he kissed the princess awake, he was killed by her. Why? ⑤ During a war, two officers who had killed countless people were trapped in the wilderness. They were isolated and helpless, driven nearly insane by fear and despair. One of them could not survive and died first. The other, plunged deeper into despair, buried his comrade and was close to a mental breakdown. Even more terrifying: the next morning, when he woke up, he found his dead comrade sitting beside him, staring at him with the same eyes of despair. What happened? ⑥ A girl's parents were both on a business trip. She slept alone at night, accompanied only by her beloved dog. In the middle of the night, she suddenly heard drips coming from the ceiling. To calm herself, she extended her hand to the edge of the bed, letting the dog lick her hand, and then she was able to sleep peacefully again. The next morning, the girl found her dog's corpse hanging from the ceiling, analyzed to have been killed in the middle of the night. But at that time, wasn't the dog still there? What happened? ⑦ A boy loved football very much. One day, he decided to go to the store to buy a new one. The female store owner sold him the last football in the store. He happily played with it all afternoon. In the evening, the boy returned home and turned on the TV. When he saw a piece of news, he immediately broke out in cold sweat. Why? ⑧ A woman had been living alone for a long time.One day, a friend of hers came over to visit, and the two of them chatted until very late. At 11 p.m., when the friend was taking something from under the bed, she suddenly said that she wanted the hostess to accompany her outside to buy juice. By that time, the store was already closed, but the guest still insisted on going, saying there was a kind of juice she absolutely had to drink. Why?
