The fourth dimension?

The area of timespace that has nothing and consists of no matter is called 0 dimension.if we place any given point in this empty space, that point represents a location in the first dimension. If we were to create a plane of existence from one 1st dimensional point to another along x and y axis, we enter the 2nd dimension.if we create a third point using x, y, z axis, we would have a 3rd dimensional object. We live in the third dimension, and according to einstiens theory of general relativity we are living among the x, y, z axis, simultaneously moving along a 4th axis, T, or time. This is true because any physics equation can be used to determine T through a formula. So while we are conscious we can see in the 3rd dimension and move through the 4th. But what about when we are unconscious? If I am sleeping I can have vivid dreams, where the rules of physics may not apply, and when I awaken it feels as if I were only gone for a moment.even though I'm sleeping and have not moved in the 3rd dimension, my subconscious has altered the 4th dimension and is able to jump across it in a second. Perhaps when we are dreaming our subconscious can see our 4th dimensional selves moving through time. This would also help to explain the phenomenon of deja,vu.I believe that the final frontier is not space, or the oceans, but our minds. The key to controlling and seeing the 4th dimension lies within our subconscious, though I do not have the mathematical expertise to unlock it
