Random, but a really handy way to make things seem creepy or wrong in horror is to make them incongruously neat or clean:
In the middle of a horrific battlefield, you find one corpse laid aside neatly, straightened and arranged, its arms crossed neatly across its chest
As you walk through the garden, you gradually realise that the oddness you’ve been noticing about the trees is that they are all perfectly symmetrical
As you move through the abandoned house, you realise that suddenly that there’s no dust in this room, no dirt or cobwebs
You hear hideous noises coming from behind a locked door, screams and pleas, and visceral sounds of violence. When you manage to break down the door, there is no one there, and the room is perfectly spotless
In the middle of a horrific battlefield, a hollow full of churned mud and blood, you find five corpses cleanly dismembered, each set of limbs or parts neatly laid out in their own little row
You witness a murder, a brutal, grisly killing that carpets the area in blood. When you return in a blind panic with the authorities, the scene is completely clean, and no amount of examination can find even a drop of blood
You run through the night and the woods with a comrade, pulling each other through leaves and twigs and mud as you scramble desperately towards freedom. When you finally emerge from the forest, in the grey light of dawn, you turn to your companion in relief, and notice that their clothes are somehow perfectly clean
You hand a glass of water to your suspect, talking casually the whole while, and watch with satisfaction as they take it in their bare hand and take a drink. There’ll be a decent set of prints to run from that later. Except there isn’t. There are no prints at all. As if nothing ever touched the glass
You browse idly through your host’s catalogue, and stop, and pay much more attention, when you realise that several items on a dry list of acquisitions are ones you’ve seen before, and it slowly dawns on you that each neat little object and number in this neat little book are things that belong (belonged?) to people you know
Neatness, particularly incongruous neatness, neatness where you expect violence or imperfection or abandonment, or neatness that you belatedly realise was hiding violence, or neatness that is imposed over violence, is incredibly scary. Because neatness is not a natural thing. Neatness requires some active force to have come through and made it so. Neatness implies that the world around you is being arranged, maybe to hide things, to disguise things, to make you doubt your senses, or else simply according to something else’s desires. Neatness is active and artificial. Neatness puts things, maybe even people, into neat little boxes according to something else’s ideals, and that’s terrifying as well. Being objectified. Being asked to fit categories that you’re not sure you can fit, and wondering what will happen to the bits of you that don’t.
Neatness, essentially, says that something else is here. Neatness where there should be chaos says that either something came and changed things, or that what you’re seeing now or what you saw then is not real. Neatness alongside violence says that something came through here for whom violence did not mean the same thing as it does to you.
Neatness, in the right context, in the right place, can be very, very scary
