Although Ficowski did not consider himself a prose writer, he was successful as one. Not only did he prove himself as an essayist when writing about Gypsies, Schulz and Wojtkiewicz, but he was also able to compose dream-like stories and recount folk tales he had heard from an old woman. This was yet further proof of his literary versatility.
Ficowski employed various genres of prose. In Wspominki starowarszawskie (Memories of Old Warsaw) he turned into a reporter to write an account of people who had preserved the spirit of the pre-war city. In Bajędy z augustowskich lasów (Tales from Augustów Forest) he revived folk stories told to him by an old local woman, Jadwiga. With short pieces in Dobrodziejstwo inwentarza (The Benefit of Inventory) he recalled ancient artefacts salvaged from bygone worlds. A volume entitled Czekanie na sen psa (Waiting for the Dog to Sleep) became his most notable prose work. Those semi-visionary short stories (as Bogdan Wojdowski called them) “sneak across the border dividing poetry from prose.”
