How does guy de Maupassant create suspense and surprise at the end of an uncomfortable bed

The author creates suspense by providing possible scenarios of what may happen. The narrator examines the room in great detail, and the reader gets a sense that something can happen at any moment. The room becomes quiet and dark and, even as he goes to sleep, the narrator is convinced something will happen. Instead of immediately telling readers what happens when the narrator wakes up, the author provides ambiguous details. “I stretched out my hand to find out what was the nature of this object. I felt a face, a nose, and whiskers which made me jump straight out of the soaked sheets, and rush in my nightshirt into the corridor, the door of which I found open.” Finally, the narrator shares that he actually caused the whole incident to happen.
