My Friend Dahmer (2017) Timeline Explained – Every Event in Order

Jeffrey's obsession with the jogger began in 1974 as his intense curiosity about anatomy and bodies evolved into a disturbing fixation. The jogger represented the object of his fantasies, which stemmed from his growing awareness of his own desires. He would watch the jogger from his school bus window, developing an unhealthy obsession that marked the beginning of his darker inclinations. This fixation would later extend to Dr. Matthews, the same jogger who had become a physician.

Foreshadowing: This early obsession with the jogger foreshadows Jeffrey's later stalking behavior and his escalation from fantasy to action.

John 'Derf' Backderf was an aspiring artist who noticed Jeffrey's odd behavior, particularly his mimicry of a disabled interior designer. Derf and his group of friends formed the 'Dahmer Fan Club,' using Jeffrey's eccentricity for comedic pranks they called 'Doing a Dahmer.' However, their friendship was largely exploitative, they snuck Jeffrey into yearbook photos and persuaded school officials to let them meet Vice President Walter Mondale. Derf later documented these events in his graphic novel. The friendship was superficial, providing Jeffrey with the appearance of social acceptance while actually deepening his isolation.

Foreshadowing: The superficial nature of these friendships highlights Jeffrey's profound loneliness, which intensifies after Derf leaves for college.

Jeffrey's collection of deceased animals began in 1974 as he tried to satisfy his intense curiosity about anatomy. He used chemicals obtained from his father Lionel to dissect the animals and study their internal structures. While this disturbing hobby raised eyebrows, it revealed Jeffrey's fascination with bodies and anatomy, a fascination that would evolve into his later criminal behavior. His father initially enabled this interest by providing the chemicals, unaware of where Jeffrey's curiosity would lead.

Foreshadowing: This early interest in dissection directly foreshadows Jeffrey's later crimes, as he moved from animal dissection to human bodies.
