Now this is something I am working on in my fictional series, where memories are recounted by someone who is enhanced with DNA from another person. Sounds far-fetched, well sure it is sci-fi but much of sci-fi is based on science, just enhanced for the enjoyment of ‘what if’.
So in my story, our hero the ever lovable warrior, has dreams and visions that appear as memories of an older time. He remembers wives and children that are not his, battles he never fought in, and many lives lived to old age, yet he has barely lived one life.
Step outside the norm and you may be surprised how science will be shadowing your move.
