On a more mundane level, here are several points I hang onto when navigating this conundrum about "time" that baffles my 3D minds:
There is no "future" or "past," only "now." Future and past are one of the 7 Illusions that came with the "Fall of Man." These are concepts--not realities--we can only exist in the "here" and "now."
If one travels far enough West (the future) from where you are now, one ends up in the East (the past).
My version of the "mirror in a mirror" thing goes like this;
In this one little box I found in 2007,
there's an old video I copied in 1997,
of a film with actors portraying in 1977,
people in a Broadway play watching in 1967,
actors on a TV show portraying in 1957,
people watching in a movie in 2057,
film actors portraying in 1927,
people living in 3007.
Or put another way,
In this one little box I found in 2007,
there are people set living in 3007,
who were portrayed by movie actors in 1927,
who are in a movie being watched in 2057,
which was portrayed by TV actors in 1957,
who are in a Broadway play set in 1967,
which was portrayed in 1977,
by actors who are in an old video I copied in 1997.
