Narration Processes: The Beginning Of The Scene

It is convenient to begin with something that arouses the interest of the reader, that makes him be aware of the continuation of that scene. What mystery does this character hold? Why does he suffer so much? How will the conflict be resolved? What was the cause of the tragedy? What does this unknown place mean?
Any interesting matter serves as the beginning of the scene. Franz Kafka, in The Metamorphosis, teaches us to start a story: "When Gregorio Samsa woke up one morning, after a restless sleep, he found himself in his bed turned into a monstrous insect. He was lying on the hard shell of his back, and, raising his head a little, he saw the convex figure of his dark belly, furrowed by curved calluses, the prominence of which could barely support the quilt, which was visibly about to drain to the I usually. Countless legs, woefully scrawny compared to the ordinary thickness of his legs, gave her eyes the spectacle of inconsistent shaking.
"What has happened to me?"
I was not dreaming, no. His room, a real room, although excessively small, appeared as usual between the four well-known walls of his. Presiding over the table, on which was scattered a sample of cloths • —Samsa was a traveler from trade - there was a picture that had recently been cut out of an illustrated magazine and placed in a beautiful frame Golden. This picture represented a lady wearing a fur cap, wrapped in a fur boa, and what. standing very erect, it would hold against the viewer an amnion cuff, also made of skin, within which his entire forearm disappeared.

Everything in the above transcript keeps the reader curious and prepares him for the next scenes.
I offer another suitable scene opening in Edgar Alian Poe's The Mysterious Brick:
"For some time later an incident occurred that filled me alternately with joy and horror, and for this reason seemed more moving and terrible that none of the hazards that I have run later in the course of nine long years, full of events as surprising as unheard of. We were lying on the deck, next to the esra'a. discussing the possibility of entering the pantry, when turning my eyes to Augusto, who was in front of me. I noticed that he had suddenly turned dead pale and that his lips were trembling in a singular and incomprehensible way. Quite alarmed, I spoke to him and he did not answer, which made me think that he had been attacked by a sudden evil. Then I noticed his eyes, singularly bright and fixed on some object that was behind me. I turned my head, and I will never forget the unspeakable joy that penetrated my whole being seeing a great brick that was coming towards us and was no longer even two miles away. "{Cf.
