One day, when you saw Xiao Ming littering everywhere, you went over and said

There are many answers on the Internet, but these two answers are generally accepted.

1 Grandma Wang is a killer. She has a hobby of keeping people in the house and torturing them to death. As soon as she tortured a person to death that day, she cleaned up the blood and minced meat with white paper and dumped it, which was seen by Xiao Ming. Grandma Wang pretended to praise Xiaoming for demonstrating, but the man he tortured today didn't die. He ran out while Grandma Wang was not looking (there was a time difference here, so we can think that he ran out when Grandma Wang was cleaning up the traces of torture). On the second floor, Xiao Ming saw this man, but probably because of the dim light, he didn't notice that this man was actually incomplete. For example, in 1 building, Xiao Ming saw the piece of paper covered with flesh and blood, and he suddenly remembered the people on the second floor. Sometimes our brains are in a relaxed state, which probably reflects dullness. It only takes 1 0 seconds at1floor. ) I didn't find any difference between the people on the second floor, I think it is possible. If he had seen this man invited to his home by Grandma Wang, it would have been really scary.

The garbage thrown by grandma Wang is actually a person who seems to put up a small advertisement, but it is actually grandma Wang's enemy ... that person was thrown down, climbed out of the garbage tunnel and went back to take revenge on grandma Wang. His hands were covered with blood, like putting up a small advertisement on the wall, and Xiao Ming didn't see it clearly because it was night. The red paper may be blood-stained paper that was taken out of people and fell on the first floor. Xiaoming went to the first floor.

But there are also logical errors. Anyway, don't think with normal thinking, just expand your imagination.

At first, I thought it was the sensory deviation of space that made Xiao Ming mistakenly think that he was on the negative floor. In fact, this happens from time to time in reality.
