To me personally I believe this could be a possibility although not always attributed a definitive means as to how an individual died per se - A birth mark on an arm/leg not really evidence enough of a fatality
- I believe that we bring innate personalities back to this life from other lives so why not projections of a physical form? I would think (again, merely a personal perspective) that if the birthmark was attributed from a past life it would be to accompany you through this life for a reason - an innate understanding of something - maybe it is a means to recollect something? I would not know
Have you ever looked into regression hypnosis?
So funny, I've just been wondering about this and looking into it a bit. I saw something in which researchers said I think in around 30% of cases where someone had a birthmark and could remember details of previous lives, they found injuries matching the birthmarks. I don't know how many people were involved in the study though.
My son has a birthmark on his leg. I wonder whether it could reflect a severe burn in a previous life. My mum's a nurse and she also thinks it resembles a burn in form, though it is not a burn and is definitely a birth-mark.
