What could aqua Neptune conjunct Pisces Uranus mean? (That’s the only aspect my Neptune has)
Neptune conjunct Uranus
First off, this is a generational aspect because both Neptune and Uranus move very slowly through the sings. This means that this aspect is less personal/individual.
Second off, with generational planets the houses and aspects to faster-paced celestial bodies are much more meaningful in their expression. (it's also generational that those two planets are in mutual reception but it's worth looking into that if you're interested)
I also recommend you look up minor aspects as they are often overlooked but at the same time more important than one might think (they might help you to understand what things you might be tripping over in the dark).
Keep in mine that this is also depends a lot on the house these planets are in: Neptune conjunct Uranus suggests an idealism and possible delusion when it comes to identifying problems in society/a system that you strike to change. It's possible that you have fantasies of rebelling and breaking free from restrictive structures in your life. A good thing here is that you wholeheartedly believe in what you individually stand for. Both Neptune and Uranus are afflicted with wishes and dreams, just that Uranus is about actually taking abrupt action and falling out of line, using the ideals as a backbone to the change, while Neptune is about the illusion of wishes and dreams, the part of them that lives in your head: your beliefs and delusions as you simply dream on, caught up in your own perception of things.
Hope this could help a few!
