Knocking comes from the basement. It always comes from the basement. Of course horrible things can happen in broad daylight with lots of people around. But that isn’t expected. Horror is supposed to be confined to the dark places, to when we are alone. Hence, basements. See also, under beds at night.
Perhaps if we could see the monsters, they would not be terrifying. It is, after all, the unknown which frightens most of all. If the monsters were in the light, they would lose their power altogether. Vampires burst into flame in the sun. Werewolves change only at night.
The knocking continues. It is after midnight and dark outside. Inside, all the lights on the first floor are on. Surely that will keep away whatever wants up. The basement, the attic, all places where we put things forgotten. Or things we would like forgotten. Things we think we don’t need, or things we don’t like. So naturally that’s where the monsters live, among the things we want gone but cannot bring ourselves to throw away.
It’s more insistent, just on the other side of the door. What has been forgotten that now demands to be remembered? What is it that was ignored, cast out, with the hope that it would stay forever buried? Perhaps some behavior society says was not nice, or maybe a desire the world scoffed at.
The doorknob jostles. To barricade or open? Barricading is obviously the safer path. But taking the safer path is what brought us to this point. Getting rid of all that scared us, putting it into the basement, it has festered. Now it is knocking. What further violence must we commit to force it back down where it belongs?
Or we could open it. What would we see? Our monstrous self, revealed in the light. Coming face to face with all we have denied, would we ask for forgiveness? Would we get it? Or would the monster destroy us? There is only one way to find out, but opening that door… No one really knows what’s on the other side. And that is the source of our fear. We have created the monster, and now we fear what it will do to us because we don’t know.
If we had been rejected and locked away, we would be angry. Thus we imagine the monster will destroy us out of anger. But we don’t know. We never gave the monster a chance. And now it demands one. Open the door. Let in the light. Face what we have made. Nothing worse can be done to us than what we have already been done. We are the monster. We made ourselves that way. Open the door.
