Pisces is the last sign — the energy that contains all the others, dissolved together. Neptune rules you, and Neptune is the planet of dreams, oceans, the things that have no firm edge. You arrived with a porous boundary between self and world, and your task is to use that as a gift rather than a wound.
The shadow of Pisces is escapism — addiction, fantasy, dissolving into other people's feelings until you can't find your own. The mature Pisces has learned that boundary doesn't mean wall: you can stay open and still know where you end and another begins.
You'll recognize yourself in Pisces if movies wreck you for hours, if you've been known to absorb the moods of strangers, and if you have a private inner world that's as real to you as the outer one.
