Reality

What truely is reality?
Is it what you belive it is,
or is it a standard illusion
blocking the mind frow free falling
into a sea
of imagination.
I bought my pet a cage.
I stared at it.
Just waiting for something
to break the mold
break reality.
Then it came to me.
I don't know which side of the cage
I am on.
Perplexing.
This world seemed so
set in stone.
But I guess that's
my own reality.
