I believe in family karma more than past lives. I'll tell my experience of it.
Mine is more about discovering problems in my family roots. My NN conjuncts Venus in 8th house and in oppositon to Saturn in 2nd and both squares Jupiter in 4th.
In September 2008, Saturn started to trine my NN and Venus. I found myself at astrology course and energy works. But before going to my first energy work, I called some of my family members from mother's side to learn if something weird happened to anyone in my family past.(My teacher and master has told me that the things happened in the family past is important so that was the reason of my searching)
I learned nothing significant but at that night I saw an interesting dream.(I have to say that I never see nightmares in my life) My dream told me that a grandpa in the family past didn't die normally. Although he has a long time for living, he dies because of a curse made. (it's a curse which is made with soap and thrown into a shaft then) It was a terrific dream and when I woke up I shievered for a while. It's energy stays in me the next day. I couldn't sleep the next night, when I closed my eyes, I was seeing faces, words, things like that, I slept with my mother that night.
Then, for 2-3 months, I saw really interesting dreams. Mostly about my family roots. After a month or two from my first dream I told above, I saw another one. And in this one, I was told that the other people who made the curse in the past is dead now because my subconscious has influence on them. After that dream, a few days later, in my , in my mother's and in my aunt's dream, we both saw a celebration made in the family without knowing each other or knowing the situation.
I have to cut it short. After that I go on seeing other things but I'm highly obsessed and had to go to a doctor. I had to say that I was doing energy work for increasing fire element in me, try to open the root chakra and when I stopped it, dreams are also stopped, too. But I feel there is still something unsolved.
For interpretation, my North node and south node both are both in connection with 4th house, family roots. As Saturn effects it, it means I can't be able to fed from my family, there is an obstacle. And I have to solve it. Also 8th house is about death and my dream was about a dead of someone from family past. Also when Saturn conjuncted my NN in 1999-2000, I committed suicide. So NN in 8th house has something to solve about death for sure.
But there is another thing, as my Chiron is also in 8th and Venus, I think there is a problem with love, feminity and sexuality. When I look at the women's life in my family, they all have problems with marriage and love. And I have, too. I don't know how to solve it but I'll try it.
And almost all of my family members are passive and shy. I'm the first one who tries to break it, so there is a connection for sure. And also most them are bad at showing love-again Venus-Saturn aspect.
I'm examining my mother's and father's chart, and I think my chart is the mix version of them. There are so many common things.
I believe the duty of solving family problem is given to me. I feel them soo in the surface and my everday life is almost passes with trying to solve psychological problems.
Thanks for reading this, for me it's an important thing to share my experience.
