Dimensions are mental constructs. A dimension is a measurement of something. These measurements are in the mental world of conscious awareness. We can only measure things with our conscious intellect. When we become aware of a dimension, it is a viewpoint.

This parade of dimensions begins with the zero-dimension, a non-dimensional viewpoint without material content. For dimensions to come into view, both awareness and information processing is required. That is why the zero-dimension is a mental world of awareness. It precedes the existence of being. This non-material zero-dimension is without time, without space and is eternally present everywhere at once. The zero dimension is the source of the awareness that projects the universe into being.  

This is where each of us came from before birth and possibly the same non-place that we dwell in when we die. We all remember this place. Since we have all experienced the place where our awareness of ourselves was united with everything before we began to exist in this time and space. Everyone has experienced an infinity of endlessness. 

Timelessness can be pictured as a sleeping form of awareness that—when  awakened—develops into the recognition of sensory touches and perceptions. In time, awareness births the subconsciousness and the self-consciousness. 

As the universe is born from infinity, we are as well. Infinity is that which was before this life experience. The world about us is similar to a continuous dream that is made real by our consciousness awareness.

Because the zero dimension is static and unchanging, the first and second dimensional structures are also timeless in that they are everywhere at once.

To see something in three dimensions, one has to view from outside and above the apparent dimensions. A circle on a plane—like a drawing on paper—does not appear as a sphere until viewed from above the plane. The added dimensions of height, width, length, and duration create a space that becomes visible in three dimensions while height, width, and length are being experienced. 

Duration is not only an element of time but it is also an element of length. “Length” commonly refers to physical size, as in the length, the width, and depth of an object. Duration measures the time period, but the term length  is also used to define a period of time as in: “How long have you been waiting?” 

When and space and time are molded into a common dimension, they become that fourth-dimensional viewpoint which Einstein called spacetime.
