I suspect we all have the potential and it's more highly developed in some than others. When my younger daughter was a child she often replied to things I hadn't said yet or would come in from playing thinking I had called her when I was just getting ready to call. My partner and I have been together for 30 years and frequently one of us will say what the other has opened her mouth to say. It's eerie and often unrelated to what's happening around us. I think in the future folks will learn to develop these gifts.
