Shadow Universe

Our universe creates 2D projections: shadows. Shadows make up their own world. Like a parallel universe, but with one less spatial dimension. The 2D universe of shadows exists as a consequence of events in our 3D universe. When a 3D object blocks a photon it creates a 2D shadow. Is our 3D universe the shadow of a 4D universe existing parallel to our own? Are we merely the effect of events in the 4D universe? In our universe we dictate what 2D shadows are created. The “natural events” of our universe may actually be cognitive changes by 4D beings in a 4D universe.
