Rules:Pisces/ 12th house
Natal significance: Neptune in your birth chart shows your dreams, fantasies, and delusions. As a slow-moving generational planet, Neptune shows the collective unconscious of a generation -- its dreams, fantasies, and delusions about itself.
Transiting significance: Where Neptune passes in your chart shows what realm of your life is most bound up with the dreams and fantasies you have in this period of your life. as well as where you may tend to delude yourself or be easily deceived (watch your romantic life when Neptune transits your fifth, seventh or eighth house.) When other planets form aspects with transiting or natal Neptune, the combination of energies gives you a chance to unmask these delusions and clarify to yourself the way you deceive yourself.
