Those damn grey aliens. Always been scared of those. You know you'd lose it if you woke up in the middle of the night and saw some dark silhouette at the side of your bed, perfectly still, staring at you with its head leaning to the side.
You'd keep staring at it, waiting for your eyes to adjust, thinking "That can't possibly be there. I'm just seeing things. Besides. It's not moving."
So you lean over to turn on your lamp, and lean back and there it is, even CLOSER, leaning in toward you, its huge black eyes boring into your soul.
And then, in a lightning fast movement, its hand shoots out and grabs you and drags you up to the ship.
