I also had a story with "Upyr" (read, it seems, in ninth grade). Shortly thereafter, she was sitting at home in the evening alone at the desk, naturally, at the window, the curtains are stuck, from the lighting - only the desk lamp. The parents are away, the grandmother is at work, quiet, dark. And suddenly right next to my ear, from the side of the window, there is a quiet short whisper. At that time I understood what it meant to shrink from horror, I could neither shrink nor move. Fortunately, after a few seconds, the cat himself came out of the curtain and lay down under the lamp, apparently sitting on the window.
