Welcome, 🙂here is a link that answers exactly your question :

My own experience confirmed it as well, before I ever saw this thread.
I'm specially interested in past lives, so I often looked at SN-, Saturn- and Karma- placements.
For example I once found my Karma conjunct a planet of somebody, and this planet was in a difficult position in that persons chart.
So he had problems to live the energy of the planet properly and was unhappy because of it.
I was able to help and it had to do with a past life we had. The SNs were also involved and I remembered parts of those lives.
So she could help you with your NN and you her with her Pluto.
You said all conjunctions at the same degree, did you mean the degree in the signs or the orb of the conjunctions so tight ?
I guess you mean the degree in the signs, but how about the orbs ?
Who is Moon, who Mercury ?
How about the SNs and Saturns and the other Vertex ?
You can also post charts here and remove them later, in case you like.
