Lime Green Eyes

Creeeeeek.

Floorboards shiver and groan under feet, not necessarily yours. Over time, while your body's been growing physically, your ears have been growing to learn the sounds each board, every step, makes with a given amount of weight. Using common logic, you tell yourself that the dark is nothing but an absence of light: no monsters, creatures, or claws could be lurking within them.
But those eerie sounds, and suspicious shadows crawling across your walls tells a different story. What if...what if there is some ferocious beast just behind the closet door, that's taking it's time in opening the door, inch by inch until you go mad. What if some slimy, shark toothed lizard is snoozing under your bed, inches from your tasty ankles. Waiting for you to dangle them teasingly over the edge, so it could crunch the fragile bones, and suck out the marrow within.
One could possibly be the shadows itself. Maybe it jumps in your room to gobble up the lights so his friends can party through the night, pillaging your mind. It's furry, midnight black skin, and beedy, lime green eyes staring from eight or nine feet in the air grinning to show off missing teeth. My oh my, he'd think out loud, don't you look scrumptious...
