That Dense Darkness

I am that line
you may have heard somewhere,
but never yet have used in any poem of yours.

I am that word
you've always thought simple,
though you don't really know how to spell it.

I am that feeling
that clings to your whole body with tender care,
yet you have never met it face to face.

I am that deep darkness
where you long to sink and live...
knowing that drowning is not easy.
