What's hiding in the dark?

You pull the blankets up to your nose
But your eyes stay wide
They dart around looking
For something that may 
Or may not be there

Was that a sound?
You feel a scream building up in your throat
You push it deep into your stomach
Leaving an empty screaming ball inside

The darkness closes in
Filling your lungs
Covering your mouth 
Stopping the scream that slips back up
It grabs at your hair and ears
Daring you to move

But your body is frozen
'Move' you think
'Move'
Your muscles stay tense

Every noise is amplified 
You swear to yourself 
You won't fall asleep
And fall into its trap
