The wooden mermaid figurine that Winslow discovers in a hole in his cot serves as a catalyst for his psychological unraveling. It becomes an object of obsession, representing both his desires and the blurring line between reality and fantasy. Winslow experiences visions and dreams involving the mermaid, which symbolize his inner temptations and the seductive yet dangerous allure of the unknown. The figurine anchors the film's themes of isolation, sanity, and supernatural temptation.

Thomas Wake is fiercely protective of the lighthouse's light, constantly ascending to tend to it, often nude, and forbidding Winslow from ever looking directly at it or touching it. The light represents power, knowledge, and perhaps immortality to Wake, he views it as his divine right and purpose. This obsession creates conflict with Winslow, who grows increasingly curious about the light. Wake's refusal to share this responsibility reflects his desire to maintain control and dominance over both the lighthouse and his companion.

Foreshadowing: Wake's obsessive guarding of the light early on foreshadows the climactic struggle at the top of the lighthouse.

At the climax, Winslow desperately tries to escape the island but is thwarted by the relentless storm. He finally reaches the top of the lighthouse, where the blinding light overwhelms him completely. Consumed by madness, he laughs hysterically as the light engulfs him. The film ends with Winslow left vulnerable on the island, surrounded by seagulls, his fate uncertain but seemingly sealed by the elements and the creatures he offended. The ending suggests he has been completely consumed by madness and the harsh environment.

Foreshadowing: The escalating psychological warfare and Winslow's attempts to escape foreshadow this climactic moment of complete breakdown.

The film deliberately blurs the line between reality and hallucination, leaving much open to interpretation. Winslow experiences increasingly vivid hallucinations, including visions of the mermaid, seeing Wake transform into different entities (including the real Ephraim Winslow), and distorted perceptions of time and space. However, certain events, like the killing of the seagull and the storm, are depicted as واقع (real). The ambiguity is intentional, reflecting the film's themes of madness, isolation, and the breakdown of perception. Viewers are meant to question what is real throughout.

Foreshadowing: Early surreal moments and Winslow's unsettling dreams foreshadow the complete collapse of reality perception.

The relationship between Winslow and Wake deteriorates due to multiple factors: extreme isolation, mounting work exhaustion, alcohol consumption, and clashing personalities. Winslow resents being assigned the grunt work while Wake tends to the light. Wake's eccentricities, superstitions, and nighttime excursions frustrate Winslow. As Winslow's mental state declines, he becomes paranoid and suspicious of Wake. Alcohol fuels heated confrontations, exposing deep-seated fears and vulnerabilities. The power struggle intensifies until both men are locked in psychological warfare, each questioning the other's sanity.

Foreshadowing: The rocky first meeting and early tensions foreshadow the complete breakdown of their relationship.

The film creates confusion about identity: the protagonist arrives on the island claiming to be Ephraim Winslow, but Wake occasionally addresses him as a different person, and Winslow himself experiences visions of another man. During his hallucinations, Winslow sees Wake transform into the 'real' Ephraim Winslow, suggesting the protagonist may have taken someone else's identity. This identity confusion is part of the film's psychological ambiguity, the true identity of the protagonist remains uncertain, possibly a result of his deteriorating mind or a deeper secret from his past.

Foreshadowing: Early hints of identity confusion and Winslow's mysterious past foreshadow this revelation during his hallucinations.

The lighthouse light functions as a central symbol with multiple layers of meaning. It represents knowledge, truth, divine power, and enlightenment that Wake guards jealously. For Winslow, it becomes an object of both desire and terror, something unattainable that drives his curiosity and eventual madness. The overwhelming brightness at the climax suggests that true enlightenment or revelation can be destructive. The light also symbolizes sanity itself; when Winslow finally faces it directly, he is consumed by madness, implying some truths are too harsh to bear.

Foreshadowing: Wake's insistence that Winslow never look directly at the light foreshadows its destructive power.

The relentless storm traps both men on the island, cutting off any possibility of escape and intensifying their isolation. The howling winds and crashing waves create an atmosphere of constant dread and sensory overload. As the storm rages, Winslow's mental state deteriorates rapidly, he experiences vivid hallucinations, sees Wake transform into monstrous forms, and loses grip on reality. The storm acts as both a literal and metaphorical force, amplifying the psychological warfare between the two men and accelerating their descent into madness and violence.

Foreshadowing: The increasing severity of weather events foreshadows the storm as the catalyst for complete breakdown.

Wake warns Winslow that harming seagulls is forbidden because they carry the souls of deceased sailors. This superstition adds to the film's atmosphere of supernatural dread and maritime folklore. When Winslow kills the seagull despite this warning, he commits a transgression that unleashes the film's horror. The seagulls at the end, surrounding the vulnerable Winslow, suggest a form of supernatural retribution or the return of the souls he offended. The superstition reinforces the film's themes of ancient maritime beliefs, guilt, and the consequences of breaking sacred taboos.

Foreshadowing: Wake's early warning about the seagulls foreshadows both the act of killing and its consequences.
