My monstrous roommate

Today you were lying on your bed, looking up at the ceiling, waiting... You go on living knowing that it will come soon, there is no point in running away. It is always there, sometimes knocking on your door, sometimes watching from the rooftops. It's in your closet, in your books and spoons. Your heart trembles, and the silence is torn by its roar... It's always there,it's your monstrous neighbor.
