I dreamed that someone else had his leg cut off.

There is an old saying in China that dreams are upside down. Dreaming that someone else took his leg off shows that this will not happen in real life. We are now a society ruled by law. If someone really wants to hurt you, he will also be punished by law. The reason why you dream about this situation may be that you have some friction with others in real life, and you are afraid of each other, so you think about it every day, dreaming at night and dreaming of being hurt.
