The 4th Dimension?

There has been talk of the 4th dimension and what that means to us as corporeal beings of this plane and 6th age. So to my understanding, the literature of the 4th Dimension speaks on the concept of mortal consciousness as: being able to perceive itself BEYOND our current understanding of volume [being measured as a length times width times height metric].
 
The simplest way to describe this 'construct' is to draw two ordinary 3D cubes in 2D space, one encompassing the other, separated by an "unseen" distance, and then draw lines between their equivalent vertices. The eight lines connecting the vertices of the two cubes in this case represent a single direction in the "unseen" fourth dimension.
 
I am a man of facts, history, and the sciences. Yet, I must say, I do believe that what we are collectively experiencing is a 'slip' through what we know of as "time." I use that term loosely, as it is a "man-made" construct . But, for the purposes of linear thought I shall consider "time" as we refer to it presently.
 
As our dimension or reality pulls forward through the hypothetical timeline-of-life, we quite literally pull our 3rd dimension through the 4th dimension. This economy of motion causes rips that those sensitive to, or observant of, may witness. I have witnessed such outer-dimensional beings with my blind eye. Two of my compatriots, respectively, have looked through certain types of glass accessories to peer within.
 
Maybe my mirror will yield the same results? Only one way to find out.
