Sleep. It's something most take for granted, and it's something I have to avoid.
As soon as I close my eyes, I can feel it; staring hungrily from its perch beside my bed. Its wide eyes and jagged teeth aching for me to accept the blackness of sleep's embrace. The longer it waits, the more vividly I can see its horrid face in my mind's eye.
If I roll over and hazard a glance, it will dart back into the shadows, out of sight, waiting for another opportunity.
I have to stay on the fringe of consciousness; God, I'm tired.
