It has no dimension. It does not move. You say, well, we have proof that there was a past, and we are confident that there is a future. The moment that engulfs you stays with you and provides you with the mechanism to experience some of these probabilities. You bring your time into this experience and you take it with you when you leave.
Time has no more dimension than a thought.
No more so than you can manufacure time in a testtube. They are one in the same, thought and time, without which, there is nothing. We are prisoners of our five senses in the material realm, and we know by experience that we should not totally trust them. Time is an extension of the observer which enables the observer to observe. Without the observer, there is nothing.
