Brain Damage (1988) Timeline Explained – Every Event in Order

Elmer, the parasitic creature, slithers up Brian's back while he's in his bedroom. When Brian examines a wound on his neck, Elmer proposes a deal: if Brian takes him outside, Elmer will give him euphoric sensations described as 'light.' Brian agrees, and Elmer attaches himself to the back of Brian's neck, puncturing it with his needle-like tongue to inject a blue substance directly into Brian's brain.

Foreshadowing: Earlier, Brian experiences a hallucination of blue water flooding his room and sees a glowing eye, foreshadowing his connection to Elmer.

Aylmer (pronounced Elmer) is an ancient parasitic creature that Dr. Morris Ackerman reveals has existed since the Crusades. It's a one-foot-long parasite with mesmerizing blue eyes that feeds on human brains. Morris kept Elmer as a pet and had been feeding him animal brains to keep him weak and controllable, though this made Elmer hungry for human brains.

Elmer explains to Brian that he was deprived of human brains and kept weak by being fed only animal brains. This starvation made him insatiably hungry for human brains. The human brain provides something essential that animal brains cannot, the creature needs this specific nourishment to survive and maintain its power.

After Brian wakes from sleep with blood trickling from his neck and experiences a hallucination of blue water flooding his room, he goes to the bathroom to examine his wound. That's when Elmer, who had escaped from the Ackermans' apartment, slithers up into Brian's room and approaches him, offering the deal that begins their destructive relationship.

Foreshadowing: The Ackermans' frantic search for the missing Elmer earlier in the film sets up this encounter.

When Elmer punctures Brian's neck, he injects a blue liquid that creates intense euphoria, Brian describes experiencing bright colors, dazzling lights, and an exhilarating rush while running through a car junkyard. This 'light' sensation is highly addictive, and Brian becomes dependent on it, eventually committing increasingly violent acts to get more.

Brian becomes addicted to the euphoric sensations Elmer provides. Despite witnessing gruesome killings, including the security guard and a woman at the club, Brian cannot stop because he's physically and psychologically dependent on the blue substance. When he tries to detox, he experiences agonizing withdrawal and ultimately succumbs to Elmer's demands for more brains.

In the climax, after Elmer kills Martha and chaos erupts, Brian holds a gun to his head in despair. The police arrive as a gunshot rings out. The film ends with Brian's head revealing an eerie pulsating light from within, showing that Elmer has taken complete control and transformed Brian's brain, leaving him alive but utterly consumed by the parasite.

The film uses Elmer as a metaphor for drug addiction. Brian's initial curiosity leads to dependency, he experiences intense euphoria from the substance, then suffers agonizing withdrawal, and eventually commits increasingly horrific acts to satisfy his fix. The parasite's control over Brian mirrors how addiction consumes a person's mind, free will, and relationships, ultimately destroying everything around them.

Elmer attacks when threatened or when Brian's emotional state is compromised. When Brian overhears Mike confessing feelings for Barbara, his jealousy triggers Elmer to attack Barbara. Similarly, during the confrontation with Morris, when Morris tries to protect Martha, Elmer kills her and attacks Morris as part of its predatory nature to protect itself and Brian, its host.

Elmer escapes after Morris brings home animal brains instead of the human brains he had been depriving the parasite of. Frustrated by this continued starvation and sensing an opportunity, Elmer vanishes from the bathroom before Martha can feed him, setting the stage for him to find Brian.

When Brian overhears Mike confessing his feelings for Barbara and they become intimate, Brian succumbs to violent fantasies induced by Elmer's influence while attached to him. This emotional trigger, combined with Brian's existing jealousy and Elmer's predatory nature, causes Elmer to attack Barbara, resulting in her death.
