Shadow People

They're not real
Or are they?
They couldn't be, it's all in my head
But my head is real
And my eyes can see them
Not often, only sometimes
Silently watching not far from me
Or appearing suddenly
Giving me a startling scare
Leering at me into the night
As if knowing my dark secrets
And lingering fears
Unfaltering eyes
A welcoming smile
Sending terror down my spine
My reality starts to unwind
Help me! I'm sinking into hell!
