It isn’t dark.
It isn’t light, either.
It is the tricky light; where the sky is clear as day, but earth is filled with shapes and shadows, which move when they shouldn’t.
They slink behind trees, and peer from the pale walls of white houses.
They watch, silently, as you go about your business.
Maybe they hide in the backseat of your car, so you turn around quickly when you get in, but they always vanish just in time.
Maybe you hear their cackle echo as they shoot round the corner, like a vanishing puff, and you aren’t sure if you saw something, or if the not-quite-darkness played a trick on your eyes.
The best weapon for this time of night is a warm jacket. Make sure the inside lining is soft, and make sure you drown in your jacket. It’s the only way to keep you safe from the Twilight Terrors.
