Never turn around.

When the darkness has eyes that glow and claws that catch,
 and feet that slide unseen through the night,
When their howls and moans raise the hair on your arms and neck-
that is when you run.

Have swift steps towards the light,
and don't let them smell the fear that is gnawing at your insides,
or hear the scream of mindless terror that is tearing at your throat.
They are deadly enough without any encouragement.
But if they know of your doubts and your nightmares,
then you will never be safe.
Once they have tasted that small part of you, they will use it.
It will fuel them and turn every single monster, to a never-ending hoard.
No matter where you go, they will find you.
Everywhere you look, you will find their eyes and deep-throated whispers.

Once you've met their eyes,
they will never leave you.
So whatever you do-
even if their footsteps are charging towards you-
even if their fetid breath is searing the back of your neck-
if you can almost feel the grasp of their rotten hands on your skin-
don't turn around.
And never look into their eyes.
