Neptune trine Neptune transit stimulates your imagination to see whether something greater lies ahead for you, especially in a spiritual sense. This can show up as increased empathy, sympathy, and compassion for others.
You are becoming more sensitive and may notice you are more affected by the upsetting things you see or read about that affect many people or the environment. This could lead you to get involved in charitable organizations, human rights advocacy, or environmental conservation efforts.
You should feel a greater sense of unity with your generation and, likely, humanity in general. But the subconscious connection between you and others with a similar Neptune placement is powerful. You may also form a special connection with people of any age who have a planet conjunct your natal Neptune.
Joining groups will give you the sense of connectedness you seek. This could be related to your renewed interest in religion or spirituality, which is common at age 55 with this transit. You will also likely have more profound dreams and psychic experiences, and understand them like never before.
