In Dreams

Claire's dreams begin as vague, unsettling visions of an underwater city and a young girl's murder. These dreams are actually her psychic connection to Vivian Thompson, the serial killer who has been abducting girls for years. The underwater city represents Northfield, the former town flooded to create the reservoir. This psychic link allows Claire to experience fragments of Vivian's crimes before they happen, though she doesn't initially understand what she's seeing or that it's connected to her own daughter.

The dreams start as hazy memories rather than clear premonitions, hinting that Claire's psychic abilities have been dormant until Vivian's activity triggers them.

Dr. Silverman diagnoses Claire with psychosis because her claims about knowing a killer's identity and location through dreams align with classic symptoms of delusional thinking. From a clinical perspective, a mother experiencing grief over her murdered daughter could easily construct a fantasy of having psychic abilities as a way to cope. The film intentionally blurs the line between mental illness and genuine psychic perception, making it ambiguous whether Claire is truly experiencing psychosis or if her visions are real.

Early in the film, Claire describes her dreams as feeling almost like memories, which plants the seeds of doubt about her mental state.

Claire's psychic connection to Vivian grows stronger and more precise as the film progresses. After months of experiencing his visions, she can now see where he takes his victims. The renewed surge of visions when Vivian kidnaps Ruby gives Claire clear enough images of the location, combined with her knowledge that he operates near water (connected to the flooded Northfield), to track him to the abandoned fruit factory by the lake.

The timeline shows Claire's visions becoming increasingly clear and vivid as she gets closer to the truth, shifting from hazy impressions to specific locations.

Rebecca is found dead at the bottom of the reservoir, and the film strongly implies she was one of Vivian's victims. Claire's visions of a young girl being murdered begin around the time Rebecca disappears, and her daughter is discovered in the same reservoir connected to Vivian's usual hunting grounds. While it's never explicitly confirmed on screen, the narrative suggests Vivian targeted Rebecca because of Claire's psychic connection to him, making it a deeply personal tragedy.

Claire's visions begin focusing on a young girl's murder just before Rebecca vanishes, suggesting the killer was drawing ever closer to Claire's family.

Claire drowns because she experiences a final vision of reuniting with her daughter as she falls into the water, causing her to surrender to the current rather than fight to survive. This represents Claire finally letting go of her guilt and grief over Rebecca, choosing to be with her daughter in death rather than continuing to live in a world where she couldn't save her. Vivian survives because he's younger and stronger, but his fate is arguably worse, he's left haunted by Claire's spirit in the psychiatric institute.

The film's dark melancholy and Claire's exhaustion throughout the narrative build toward this tragic, selfless end.

Northfield was a real town that was deliberately flooded to create the reservoir where Rebecca's body is found. Claire's psychic visions show her the underwater ruins of this town, which becomes a key clue that helps her understand Vivian's hunting ground. The flooded town serves as a metaphor for buried secrets and the way the past can resurface, Claire's psychic abilities essentially uncover what's been hidden beneath the surface, just like the ruins of Northfield.

The underwater city appears repeatedly in Claire's dreams, and she later discovers it's not imaginary but a real submerged location tied to the killer's crimes.

Vivian survives the fall from the bridge because he's physically stronger and manages to stay afloat, but the film frames his survival as a curse rather than a victory. He's immediately arrested and committed to the same psychiatric institute where Claire was held. His survival means he's forced to live with the knowledge of what he's done, and he's ultimately tormented by Claire's spirit, the psychic connection she had with him in life persists after death, haunting him with the words 'Sweet dreams, Vivian.'

Throughout the film, Vivian is described as childlike but cunning, suggesting he has the survival instincts to escape the water despite his fragile appearance.

The phrase 'Sweet dreams, Vivian' appears in blood on the walls of Vivian's hospital cell, representing Claire's spirit continuing to haunt him even after death. Just as Claire was forced to experience Vivian's murders through her psychic dreams, now Vivian is trapped experiencing Claire's presence as a perpetual nightmare. The message is a final twist of irony, Vivian, who made others live in terror through his crimes, is now condemned to a lifetime of haunted sleep.

The film's title and opening premise establish that dreams are Claire's weapon, and this final image inverts the dynamic so Vivian becomes the one trapped in nightmares.

The police dismiss Claire's claims because she has no concrete evidence, only dreams and visions. From their perspective, a grieving mother who lost her daughter is constructing a fantasy to cope with trauma. Claire's emotional deterioration and eventual suicide attempt further convince them she's unstable. The film critiques how easily women's mental health concerns can be used to discredit legitimate observations, though it also maintains ambiguity about whether Claire's perceptions are truly reliable.

Claire's clash with investigators occurs early in the timeline, showing the systemic resistance she faces when trying to communicate her visions.

The film suggests Paul may be involved with a fellow Australian coworker, but this subplot is largely dropped and doesn't significantly impact the main narrative. Paul's primary function is as an absent husband who isn't present to protect his family, making Claire's isolation more complete. His potential infidelity adds to Claire's emotional burden but ultimately doesn't connect to the central mystery of Vivian or Rebecca's death.

Paul's absence is established early, with the summary mentioning he's frequently away for work and 'perhaps entangled' in an affair.
