If you dreamed about dyeing someone else's hair black: Celestial objects have positive effects on you, leave your stress in your work areas aside. To see that someone else dyes their hair black in a dream indicates that a person you love will have an office, congratulate this person, take an example for your cat, and have a good and peaceful life. Not wanting someone else to dye their hair black in a dream indicates that you will be a jealous, ruthless person and encounter obstacles on the way to success.
