Thinking About Nothing And All the Parallel's In Between

What do you know about time travel?
Is it difficult to wrap your head around?
What does anyone know about anything for that matter.
We know not of our fate,
of our path in life.
We know only what we see in front of us every day,
from each step we take to the things we eat.
We know we're going to die,
at some point, someplace in time, and in some way.
We know that.
We know that because it's happened,
not because it's just known.
See what I see?
We know what's happened,
but never what hasn't.
But who's to say we can't?
Who's to say we don't?
Who's to say we aren't all living a dream,
in a simulated machine.
Who's to say we're not the parallel,
that's right, the parallel.
Of course, I'm talking about dimensions.
Who's to say we're not the parallel one?
Who's to say we're not the clone of another man,
someone who has lived already.
Possibly someone who's dead somewhere,
but alive right here, where we live.
In one dimension we're perfect, healthy, alive.
In another, dead.
Who's to say we're not all the walking dead clones,
of some experiment gone wrong.
Who's to say we're not all parallel's,
and the real you is there staring at you.
Watching you.
Correcting.
Judging.
Remarking.
And corrupting....
