Of course time is linear - it only moves in one direction.

I'd love to hear scientific reasoning (even one born out of insanity) of how you think time could move backwards.

Humans invented time by measuring how many times a certain atom vibrates in a certain amount of time.  Vibrates back and forth.  If you were to reverse time, the atom would still vibrate the same way - back and forth- and be indistinguishable from it's forward motion.  In other words, we measure time going forward (so many vibrations) regardless the way the flow of time travels.  So we can never move backwards in time.  Ever.

Dreams are imagination dank, they are not real.
