Dunne’s dreams seemed to him evidence for what Einstein and other physicists and mathematicians were just beginning to assert: that since the present moment depends entirely on where you stand in relation to events—what might be in the past for one observer may still be in the future for another observer, and vice versa—then the future must in some sense already exist. Einstein’s theory of relativity suggested that time was a dimension like space. To help visualize this, his teacher, Hermann Minkowski, pictured “spacetime” as a four-dimensional block. For the purposes of this book, let’s make it a glass block so we can see what is happening inside it. One’s life, and the “life” of any single object or atom in the universe, is really a line—a “world line”—snaking spaghetti-like through that glass block. The solid three-dimensional “you” that you experience at any moment is really just a slice or cross section of a four-dimensional clump of spaghetti-like atoms that started some decades ago as a zygote, gradually expanded in size by incorporating many more spaghetti-strand atoms, and then, after several decades of coherence (as a literal “flying spaghetti monster”) will dissipate into a multitude of little spaghetti atoms going their separate ways after your death. (They will recoalesce in different combinations with other spaghetti-strand atoms to make other objects and other spaghetti beings, again and again and again, until the end of the universe.) What we perceive at any given moment as the present state of affairs is just a narrow slice or cross-section of that block as our consciousness traverses our world-line from beginning to end. (If it helps envision this, the comic artist, occult magician, and novelist Alan Moore has recently revised the “block” to a football—one tip being the big bang, the other the “big crunch” proposed in some cosmological models.32 I will stick with the term “glass block” since I am not a football fan and “glass football” sounds odd.) Precognitive dreams, Dunne argued, show that at night, as well as other times when the brain is in a relaxed state, our consciousness can wriggle free of the present moment and scan ahead (as well as behind) on our personal world-line, like a flashlight at night illuminating a spot on the path ahead. This ability to be both rooted mentally in our body, with its rich sensory “now,” and the possibility of coming unstuck in time (as Vonnegut put it) suggested to Dunne that human consciousness was dual. We not only possess an “individual mind” that adheres to the brain at any given time point, but we also are part of a larger, “Universal Mind,” that transcends the now and that spaghetti-clump body. The Universal Mind, he argued, is ultimately shared—a consciousness-in-common—that is equivalent to what has always been called “God.
