In City A, there is a famous dreamer. He can let you live a lifetime according to your requirements in a dream. One life in a dream, one second in the world, and everything in the dream changes between the time you close your eyes and the time you open them.
The dreamer has a weird personality, sometimes he is nice, sometimes he is mean, sometimes he is very dark, no one knows his true temperament. He will not give people dreams easily, and he will not accept any money from someone who is not suitable. As for what the standards are, others don't know. Before creating a dream, he will ask the visitor to agree to one of his conditions. Different people's conditions are different. Only after they agree can they start dreaming, otherwise they will leave.
