Excerpt from The Secret Watchers by the late Halpin Chalmers:
What if, parallel to the life we know, there is another life that does not die, which lacks the elements that destroy our life? Perhaps in another dimension there is a different force from that which generates our life. Perhaps this force emits energy, or something similar to energy, which passes from the unknown dimension where it is and creates a new form of cell life in our dimension. No one knows that such new cell life does exist in our dimension. Ah, but I have seen its manifestations. I have talked with them. In my room at night I have talked with the Doels. And in dreams I have seen their maker. I have stood on the dim shore beyond time and matter and seen it. It moves through strange curves and outrageous angles. Someday I shall travel in time and meet it face to face.
