My descendant is 27 Pisces and Neptune visited that degree for months this year due to stationing. It's now retrograded off, currently 24 Pisces, but will return next year and hang out again on that degree. I was nervous about it, but it was really great and I currently miss that energy. I'm a spiritual person anyway, aided by long Neptune transit through 6th, but the conjunction amplified everything and I felt extremely connected and protected by source energy or "spirit", almost like having a special protective aura and masses of guidance. My psychic ability also amplified. Since it moved off I feel more exposed to certain harsher human energies, and less able to connect to spirit. However, that period was a bit like a training camp, so it's like I was given the tools and now it's up to me to apply them... Like the guardian left and I have to apply things on my own in test conditions. So I'm trying to do that, and looking forward to revisiting the conjunction for further training. 

I enjoyed Jupiter transiting through my 12th and conjunct my sun. I had the most vivid/amazing dreams.

This transit made me feel divinely protected. I had to go to hospital for an emergency procedure and was initially told “sorry, no appropriate specialist is here”. I began to pack my stuff and then a nurse came in and said how my usual surgeon had popped in to drop off some paperwork and she mentioned my situation, and he was willing to stay to operate on me. I was so lucky, I felt like this was the work of my guardian angels.

To have natal Jupiter in the 12th would be an absolute blessing. This transit renewed my faith and reinforced my belief in angels.
