In fact, human dreams are a very mysterious thing. Maybe it really indicates some kind of fate or mystery, or it may just be a dream of some impression made up by a rational policeman when he is asleep. It is not our dreams that predict the future, but our experiences that determine our dreams. You can think about it. Have you ever been to a place you never dreamed of? Even if you don't think you have been to that place, have you seen all the scenic spots there?
Sometimes dreaming is also an emotional release. If you dream of hitting the person you love, there may be some bonds between you. Maybe I love her so much that I'm afraid she'll get hurt. Maybe I hate him so much that I want to hit him for a long time, but I can't.
