Constructing a New Thought

I wonder how
a new thought
is constructed
inside my head
I mean
how does the thought
come to life
when just a second before
no thought was
contemplated
but nevertheless
a new thought
sparked to life
and was it without
language
just an electrochemical
process that knows
where to plug
into the dictionary
of meanings
and connect
to memories
and how do words
and memories
look in their
atomic smallness
without pencils or paper
or bits or bites
on glowing screens
and who is
the overseer
that orchestrates
this most dark
and damp
undertaking?
