* The Dream: The recurring dream of the farm, with rabbits and a garden, represents the characters' yearning for a better life, but also foreshadows its ultimate unattainability.
* The Opening Scene: The description of the idyllic Salinas River valley and the "golden hills" contrasts sharply with the harsh realities of the characters' lives, foreshadowing the cruel realities they will face.
* Lennie's Strength: Lennie's immense strength, despite his mental disability, is constantly highlighted. This foreshadows his potential for both harm and kindness, leading to the tragic consequences of his actions.
* Curley's Wife: Her loneliness, desperation, and flirtatious nature create a sense of danger, foreshadowing the events that lead to her death.
* The Death of Candy's Dog: The brutal and cold-hearted way Candy's dog is killed foreshadows the inevitable fate of other vulnerable characters, including Lennie.
* The Shooting of the Rabbit: Lennie's accidental killing of the puppy foreshadows the tragedy of his accidental killing of Curley's wife.
* The Title: "Of Mice and Men" itself is a foreshadowing device. The poem the title refers to speaks of dreams and hopes being crushed, mirroring the tragic fate of the characters.
These examples demonstrate how Steinbeck masterfully weaves foreshadowing into the narrative, creating a sense of impending doom and leaving the reader with a profound sense of tragedy.
