Speaking of the most terrifying real-life events in the world, the Ukrainian mutant spider has to be mentioned. In 1990, after the Chernobyl nuclear disaster, a man in Ukraine died in an elevator with two holes in his neck. The autopsy report showed that the man died of excessive blood loss and shock, but there were no signs of death near the body. Any trace of blood; a month later, a young woman died in the same manner in an elevator.
In response, the police believed that someone might have carried out serial murders, so they asked a police sergeant and detective to go to the elevator to check. As a result, when the elevator was halfway up, it suddenly stopped and there was a strange sound above. The police chief and detective looked above and found a huge spider. The detective immediately opened fire, but the sergeant had already been attacked by the spider, and the large mutant spider was later burned to death by fire. I believe you have only seen this kind of situation in movies, but it is really terrifying when it happens in real life!
