Time and Accention

I stay aware,
not letting my mind wonder.
I occupy time,
wide awake or in deep slumber.
I am just matter,
an vibrate just like lumber.
We both are strong,
and will build shelter from Summer.
As time goes by,
I remember I am your brother.
When our mission starts,
we must drown out all thunder.
Brighter than the sky from lightening,
our light bodies white and blinding.
Without the deepest darkness,
we would have a path to no finding.
