Monster...round the corner

There's a monster
round the corner
          ~
Lurking  in the shadows
just waiting to attack
            ~
Demon of my past
creeping up behind
            ~
My fear will everlast
engraved in my mind
             ~
Boiling blood overflow
panic stricken paranoia
            ~
Terrified to lunacy
certified as crazy
            ~
Over shoulder glances
trick vision advances
              ~
Hiding in the dark
hoping to be unseen
              ~
Its a deluded idea
I won't see him coming...
