If you dreamed about a lot of black mice: You should try to create useful things with what you have instead of feeling sorry for what you don't have, It's a waste of time trying to change people, Dear Aries. To see a lot of black rats in a dream indicates that you will take responsibility and own property, lead an ordeal life and disturb your peace. For a woman, this dream portends a job opportunity, a troubled life and a pessimistic mood for a non-working person. Sometimes, this dream indicates disaster and distress, and that you will be shown an example to your peers.
