Well, not much to go on, but I had this dream about a year ago....
The past life being discussed was not my own, but my brothers. My brother was telling me everything he could remember of this past life, and I was writing it all down. The life he was describing is one we have not 'known of' prior to this.
In the dream, he was describing to me a life as one of the Picts (an early Celtic people). We were speaking of family, and those close to him - what could he remember - he told me his partner/wife was a leader of the Picts, and that her name was 'Prinosh' (pronounced like Pree-nosh or Pree-nash). He also said something to the effect of "she waits for me to return from the battlefield", and/or "she protects my back on the battlefield". (many Celtic woman would fight just as the men.)
After a little research, I don't believe I can learn much about the name, as the early Gaelic forms of Pictish are a dead language...
I also find it interesting how someones elses past life was presented to me, unlike me own I saw no visual memory, was just writing down what he told me.
Needless to say, I told him all I could remember of what had said in the dream. He was very much intrigued!
