After a long time....a very long time (if there exists something called time!)

It has literally been years, years are a long unit of time, a practically used measurement of macro lengths of time or macro sizes of time. Length of time does not make sense as time seems to be not linear although it appears to be. For all we know, it may be a size but not length necessarily.  Does it have a size at all? Or is it just an illusion that seems to be flowing ahead linearly. Again who is to say that it does flow albeit in a circle. We perceive the flow not time itself. We imagine it to be linear but it may be circular. It may be flowing to the future to make the past happen. So time may not be there at all and all there has been is our perception of it. Just our perception, our awareness, the awareness.

Will continue just like time, will flow not like a river anymore but like time.
