I had a dream and in the dream there was total nuclear destruction of the original planet of some of our ancestors. This planet was in the Andromeda galaxy. The souls of the beings from that planet could not reincarnate there ever again, filling them with the deepest sense of loss. Their home did not exist anymore, therefore, they had to find a new home.
It had to be somewhere that could sustain lifeforms that could hold a similar holographic frequency and vibration as the souls of these beings, so they could transmigrate into new forms. There had been no suitable planets in the same star system or the same galaxy, therefore, they had to travel further afield to the Milky Way galaxy where they found the nearest suitable place to make home, planet Earth.
