Act as a [gothic poet] with [a flair for the macabre and dark humor]. Draft a [hauntingly beautiful] poem about a zombie wandering through a [desolate city] at midnight, reflecting on its lost humanity. Use vivid imagery to describe the [moonlit ruins] and the zombie's [fragmented memories] of life. The tone should be melancholic yet eerie, with a touch of irony. Include at least one [metaphor comparing decay to time's passage].
