It's not the actual sleeping that can get you. It's all before that.
Lying on your back looking at what would be the ceiling if any crack of light was given up, but no, you rest with complete darkness.
As as it deepens into your eyes and you can't tell if they're open or close at this point.
Your hands get sweaty and as you reach down to pull the blanket up further, discovering more noise than the unsteady breathing one would be use to.
Any normal person wouldn't be phased by it, however you're smart enough to see past the rustle of the blankets against your skin.
Because darkness can hide just about anything, but nothing gets past your ears.
When the buzzing stops and you sit up, breathing ceases. You can't see, but it's what you feel that makes the hairs on your arm shoot up.
It's nothing, you repeat.
It's the tree against the window, the dog squirming in his sleep.
Slowly your knees rise to your chest, arms circling your legs. Just a little bit chilly. That's all. There's nothing there and nothing to be afraid of.
After some time your eyelids fall heavy. Time seems to stand still.
That's when the ringing begins. No bells, it's not a phone call, just the pestering noise in your ears. And no matter what you do or how you position yourself, there are some things you cannot escape. The ringing being one, and the darkness consuming anything else.
As you finally find the right position that in any other persons view would look completely uncomfortable, you give in.
Eyes closed. All is still. Except for the shadows, those never seem to rest.
