To dream about the planet Mercury, this signifies that a message is about to be conveyed to you. The Greek god, Hermes is the counter equivalent of the Roman god, Mercury. As it states in mythology, both messenger gods were associated with trade and profit. Thus, seeing the planet Mercury in your dreams, represents communication, efficiency and skills in business, and logical judgment. Mercury is also an indicator of great knowledge and intellect.
Mercury is the planet of communication, information and knowledge. It is also the god of travelers and merchants. Mercury in dream means that you are communicating with people who are far away from you.
