Mind skirmish

I´ve been feeling weird lately.
I´ve been thinking and pondering,
suddenly explosions disrupt my minds eye, I cannot see.
It´s trains come off the rails, I simply cannot concentrate.
Flying tracers light up and aggravate,
in the dark corners of my consciousness.
From where I wanted cover, I´m now exposed to the pest.
"Zings" and "twangs" surround my ideas.
My connection roads are blocked by well armed fears.
It seems there is some kind of uprising and their trying for a push.
For they wait at my mind´s crossroads, hidden for an ambush.
