If you have dreamed of a mouse chasing a person in a dream: You may want to throw yourself out or if you are on vacation, you may be very happy. If a mouse chases a person in a dream, it is not liked because it is an animal that harms people's property and possessions in general, and spreads disease because it travels in sewers and dirty places. To see a mouse chasing a person in a dream means that the dreamer will get into trouble and have a hard time.
