The moon sign in astrology governs our “inner selves”—those feelings, deep desires and soul urges that not everyone sees. Much like the moon waxes and wanes, reveals and hides itself, the lunar cycles can also affect how much we share or show. Your moon sign can reveal how (and who) you love, or what you need to feel emotionally secure.
Dive into the depths! People born with a Pisces moon sign in their natal chart are known for their sensitive emotions and depth-plumbing nature. A Pisces moon sign is more mysterious than the Da Vinci Code, and their own sentiments can be even more confounding and confusing to themselves, too. Much like those born with their Sun in Pisces, the Pisces moon sign can struggle with translating their emotions into words. And yet, their empathic and psychic abilities can help them channel intuitive feelings and dreams into creative mediums like art, music, or dance. As an ethereal water sign, if your moon is in Pisces, you’re well-known for being dreamy, romantic and highly compassionate. There’s a good chance you’re attracted to “crisis junkies” who always seem to need your help or soothing support. The challenge for those born with their moon in Pisces is that they need to learn the art of autonomy, cutting the codependent cord and untangling themselves from drama divas and crazy-makers. Ruled by foggy Neptune and symbolized by two Fish swimming in opposite directions, a Pisces moon sign will need their friends and partners to be able to accept the ebb and flow of their ever-changing moods, and also allow them to open up and be emotionally vulnerable. A Pisces moon sign’s core desire, however, is that they “need to feel needed,” which makes them the most trustworthy of friends. You’re guaranteed to feel all the feels with a Pisces moon sign, grateful to swim alongside this person in their sentimental, soulful sea.
