What does it mean for my sister to dream that her brother was taken away by the police for committing an economic case?

This dream represents your brother. Every dark cloud has a ray of hope. This is the only answer in the interpretation of dreams. ..

In your dream, your father made your brother do something bad, so your brother will definitely be punished accordingly. The punishment you dreamed of was only caught by the police, so it was safe. You won't continue to do bad things, and the hard days will be over. Nightmares will wake you up. If what you dream about is not being caught by the police, but being caught and beaten by others, it is unknown. As for your father, it shows that he is a bully in your heart and likes to let people around him listen to him. He is the boss. It's a pity that he is not the protagonist in the dream. He has no misfortune or happiness, and he doesn't need to interpret dreams. Your brother may be weak recently and needs to make up for it.
