When one person’s Moon contacts another person’s Neptune in synastry, a strong compassionate, sensitive, emotional connection is indicated. The Moon person is sensitive to the Neptune person’s dreams and idealizations, while the Neptune person provides unconditional love and understanding to the Moon person. Indeed, this aspect indicates a strong spiritual and emotional bond. You feel like you can read each other’s minds, and can communicate without even speaking a word to each other.
The hard aspects (conjunction, square, opposition), however, can indicate some difficulty. In this case, there is a tendency to misunderstand or confuse each other emotionally. The Moon person may tend to be emotionally dependent on the Neptune person, for the Moon person feels the Neptune person is his or her ideal mate.
The threat of emotional deceit is high when this aspect shows up in synastry. The Moon person may not see the Neptune person clearly; the Moon person may see the Neptune person for the emotionally wonderful, supportive person he thinks the Neptune person is. In order to keep the Moon person’s ideals alive or to gain emotional support or compassion, the Neptune person may “play along” by lying, playing the victim, or pretending to be someone he is not. Even if the Moon person suspects the Neptune person of deceit, they will make excuses for the Neptune person and pretend as though nothing is wrong.
Hard aspects also indicate a great amount of possessiveness and clinginess on the part of the Moon person. Both the Moon and Neptune are highly sensitive planets, which makes this relationship excessively emotional and co-dependent. This is especially damaging if Neptune becomes elusive and distant, as it will greatly upset the Moon person. While this aspect indicates a great amount of compassion and unconditional caring, it can also lead to hurt and disappointment due to lofty ideals of what each person thinks the other person is.
The harmonious aspects (trine, sextile) between the Moon and Neptune in syanstry are wonderful additions to any romantic relationship. This aspect indicates intuitive understanding and sympathy of one another. You are attuned to each other’s feelings and moods, and show support and compassion for one another. There is likely an emotional or psychic link which enables you to sense each other’s thoughts and feelings without having to verbalize them into words.
