I want to say first that it is my experience that we are all our own unique souls, my son may not be elven despite my elven background. He has his own set of Karma and past lives that are separate from mine although we have been together before. Since I have become Indigo before his birth I know he is Crystal but that is besides the point at the moment.
I also want to say that I am very good at archery and sword play so I know my spirit or DNA remembers these things from the past. I did not hit the bullseye the first time out but I did hit the target all but once when I shot at the target the first time I even tried. I am better than my husband and many of my peers at sword fighting so I definately believe in muscle, and DNA memory. My father could fix anything, and now I can lol. I have a natural ability to know how things work.
I want to say about the energy surgery thing, I remember performing a form of energy surgery with my akashic body in a previous life. I know that might not be exactly what you meant and I am still unlocking so many things right now but I remember being in a sterile environment in space as a starseed, not sure which race but I was standing over a body with my hands above the person, but I could 'see' my akashic hands in the person, I could see everything that was happening in the body. I could see the organs which were colored blue and the bad stuff was colored gray or perhaps just different colors of gray, my hands didn't touch the good tissue at all but I grabbed the damaged stuff and removed it successfully. I have been wanting to try this technique on someone for some time but have yet been able to get anyone on my massage table lol.
I feel strongly toward my Celtic background Irish and English. But I lean more toward the Norse/Germanic deities having 'seen' Freya for some time. But, my views on deity is that they are spirits that have a more direct connection to source. Although I think it is funny that I chose one of the only other pantheons that have Elf kind. :) But I am also Germanic (kind of a mut here lol) so I am still staying within my heritage. I would love to travel northern Europe for a time.
