In reality, she remains trapped at the bottom of the cage, injured and bleeding. The film ends with her still stranded at 47 meters, making the ending a tragic one rather than a survival story.

Foreshadowing: Earlier signs of confusion and disorientation hint at the psychological effects of deep diving, though viewers may not recognize these as warnings until the twist.

The ending is a hallucination because Lisa suffers from nitrogen narcosis, a dangerous condition that affects divers at extreme depths. This causes disorientation, confusion, and vivid hallucinations. The film depicts her imagining a rescue and reuniting with her sister as her mind succumbs to the effects of deep-sea diving while she remains trapped below.

Foreshadowing: Lisa experiences moments of confusion and visual disturbances throughout the descent, which are early indicators of nitrogen narcosis setting in.

Nitrogen narcosis, often called 'rapture of the deep,' is a condition that affects divers breathing compressed air at depths beyond 30 meters. It causes symptoms similar to alcohol intoxication, including impaired judgment, euphoria, hallucinations, and loss of reality. In the film, this condition makes Lisa believe she has escaped when she is actually still trapped, leading to the film's tragic twist.

Foreshadowing: The rapid descent to 47 meters far exceeds safe limits for recreational diving, setting the stage for to occur nitrogen narcosis.

The situation at 47 meters presented extremely low chances of rescue. At that depth, the pressure, limited oxygen, and nitrogen narcosis made survival nearly impossible. The broken cage, shark presence, and Lisa's injuries combined with the technical difficulties of a rescue at such depth made the outcome tragically inevitable.

Foreshadowing: The film establishes early on that descending beyond recommended depths invites serious danger, setting realistic expectations for the grim outcome.

Yes, the ending closely mirrors the brutal conclusion of The Descent, where what appears to be survival and escape is revealed to be a psychological illusion. Both films end with protagonists in a tragic state despite seeming to have escaped, leaving audiences with a haunting twist rather than a triumphant resolution.

Foreshadowing: The tonal similarity throughout 47 Meters Down to survival horror films like The Descent prepares viewers for a bleak, twist-based conclusion.
