Neptune is my MEP. Neptune in Capricorn in the 9th house (Sagittarius). Traditionally, it's Saturn (Saturn in Capricorn in the 10th house (Capricorn)).
I'm not sure if my examples are Neptune-influenced, but I'll give it my best to explain how Neptune colors my life.
Imagination and daydreaming is a big one. I love to write stories and poetry.
I can't see my life without creating (writing, painting, drawing, flip-books/animation, doodles). I tried; my dad didn't understand why I wanted to create art instead of being interested in a normal career. When I was a teenager, I took my parents criticisms--along with my teachers' indifference to my art--to heart and stopped trying to explore art as a potential for a career. I went to college and studied Anthropology and English (minor) instead.
I focused on art the year I graduated from college and the years that followed. I created murals and backgrounds for my aunt and the hospital she worked at. I was a part of a gallery about two years back. My writing was published a year after I graduated. And throughout it all, I was still confused about what I should do. I had doubts (I still do). Sometimes I'm not sure it's worth it, but I keep going anyway.
My perspective changed recently. I couldn't keep seeing the what-ifs and the negatives. If I fall into negative thinking, my work suffers, my physical state suffers (weight loss, insomnia), and I turn to escapism (maladaptive daydreaming, reading, social media, television/Netflix binges). It's difficult; sometimes my negative thoughts get the better of me, but I try to snap out of it before it gets worse.
Not a lot of people can peg me down. Or they think they did but get upset if I don't fit their ideal image of me. People in the past took advantage of me or treated me poorly when I ignored the warning signs and focused on their potentials. I saw the good in them. It took a while to realize I didn't need those people in my life, but when I did, I walked away and didn't look back. When I was younger I was more passive, mellow.
It was difficult living in the city. I was fine at first, but over time I felt overwhelmed and drained to the point where I didn't feel like myself (if that made sense?). I fair better outside of the city, near bodies of water, or in small towns like my hometown. Not saying I can't live in the city; I did it before. It's doable, but if I live in the city I need to leave city limits once in a while or stay home to recharge.
I pray, but I wouldn't call myself traditionally religious. I look to divination (tarot, astrology). I use crystals. I have dreams that tend to come true (most of the time, not all the time). I try not to get high-end technology because they act up around me. I listen to my intuition and my dreams (if I remember them) more often than not.
I get a clearer head if I get plenty of rest or exercise (walking and riding my bike mostly). Occasionally, I feel detached from my body, so I have to walk around or do something physical to help me stay grounded. Sometimes it feels like I'm in a dream; grounding helps shake that feeling.
My days are better when I go with the flow rather than follow a strict routine. The routines I do have are loose; when I try to follow a more structured routine or plan, outside circumstances interfere and break the routine/plan and I'm back to square one.
I can't think of anything else. I attached my birth chart at the bottom if you want to take a look. Some of what I wrote above might not be Neptune, but I figured to put it all on the table. Why not?
