The premise of the Holographic Universe is that the universe is a consciousness hologram and that reality is a projected illusion within that hologram. This hologram is composed of grids created by a source consciousness brought into awareness by electromagnetic energy at the physical level. The hologram is created and linked through a web, or grid matrixes based on patterns of Sacred Geometry. The hologram had a beginning and it has an end, as consciousness evolves in the alchemy of time. As the grids collapse, everything within the hologram will end, helping to understand what is going on in the world today.

In other words, what we see in the world is nothing more but a projection of the Collective Conscious Mind. As such, what we see as a three-dimensional universe is nothing more but an image of a two-dimensional one, projected across a massive cosmic horizon. To explain it another way, we are potentially living within a computer simulation. Please see the video below for more.
