Bad Feeling - a poem

I've got a bad feeling about... something
It tickles me, inside, scares me besides
I can't place the pain I know
But inside it only grows
Something's wrong, but what I'm not sure
I don't think I've felt like this before
I've been turned away from a bad idea
Or had a feeling I shouldn't be here
But pinpoint I cannot, this feeling I feel
My imagination vivid, pain all too real
To be illusion, to be false or untrue
I'm quite at a loss as to what to do.
