Neptune in Cancer
If Neptune is in Cancer, sensitivity, emotions, and intuition is heightened, as is an inclination to worry. Neptune was in Cancer for everyone on Earth from July 1901 through July 1915, the first time since before the American Revolution. For Souls who incarnated during this period home and the family life were the driving ideals. Your dreams were of a place (perhaps a home) to be or to live in—a body. You tended to lose yourself in life, in just "being there," and feelings and intuitions were much valued. The automobile was developed, in which an heretofore ideal state, "the ride of the body", was explored and lived out. Neptune returns to each sign once every 150 years.
The three outermost planets of the solar system—Uranus, Neptune and Pluto—take 84, 165, and 248 years respectively to circle the Sun: that’s how long their "year" is. They therefore stay 7, 14 and 21 years respectively in a sign, although Pluto’s orbit is so elliptical that it resides from 12 years (Scorpio) to 32 years (Taurus) in a sign. Neptune’s effect by sign position is therefore collective, global, or generational, rather than personal.
The majority of individuals in a particular generation have Neptune in the same sign, and it therefore effects and characterizes the psyches of entire generations. Each of the outer planets, however, including Neptune, is in a different house every two hours due to the earth’s daily rotation on its axis.
