sanya, It means: "He no longer dreamed of storms and he no longer dreamed of great occurrences and he no longer dreamed of great fish, and he no longer dreamed of fights and he no longer dreamed of contests of strength." There is no grammatical reason why Hemingway omitted the 'of' before 'fights' and 'contests of strength'. It is purely a question of writing style. Often writers read their stories out loud, and if they don't like the way the written word sounds when spoken, they will change it in order to make it more pleasant to the ear. I assume that he didn't like the way "of fights" and "of contests of strength" sounded. Perhaps the repetition of the f sound in "of fights" and the repetition of the word of in "of contests of strength" irritated his ear.
