Use the adjective Proustian to describe writing that resembles the work of the French novelist Marcel Proust.
If your writing style includes long, complicated sentences full of grammatical twists and turns and reminiscences of a distant past, you might call it Proustian. Any comparison to Proust is usually based on the seven-volume "À la recherche du temps perdu," or "In Search of Lost Time." A "Proustian memory" is a brief, vivid, sense memory, especially one involving taste, based on the childhood memories that flood Proust's narrator when he eats a madeleine cookie dipped in tea.
