Termed "The Great Awakener," Uranus was named for a Greek god of the sky. Insomnia, in fact, is a symptom of being touched by Uranian vibrations. It stands for freedom and independence, and erratic unexpected change and upheaval. Ruler of Aquarius (January 21-February 18), this sign best exhibits Uranian traits of friendship and brotherhood, the fight for humane causes, and being a progressive visionary--as well as supreme individuality and rebellion against authority. Uranus stays within a sign for 7 years, getting blamed for the well-known "7-year Itch."
