Are the 'Liars' in We Were Liars ghosts, hallucinations, or something else? Possibilities explored

E. Lockhart's We Were Liars pulls you in with a mystery that builds slowly and features a final twist so brutal you'll want to reread every page. The story revolves around the Liars- Cadence Sinclair Eastman and her three best friends and cousins, Johnny, Mirren, and Gat, who spend shining summers on the family's private island.

As the pages turn, small hints disrupt the facade of their vacation. When the shocking truth emerges, one question remains: what were the Liars? Ghosts, hallucinations, or something stranger?

Answering isn't easy, as the story intentionally blends memory, trauma, and reality. When Cadence returns to Beechwood Island in the summer of seventeen, she begins to piece together what happened on the day that erased her memories.

That real story reveals that Johnny, Mirren, and Gat died in a fire two summers ago—a fire that Cadence accidentally lit herself. The Liars she has been seeing all season are not standing beside her in person. So, who exactly are they?

Hallucinations rooted in trauma and guilt

The most convincing idea is that the Liars in We Were Liars are figments of Cadence's shattered mind, born from her grief and guilt. After her brain injury and memory gaps, she returns to Beechwood, thinking she’s just hanging out with cousins she last saw two summers ago. Yet, as the days stretch, their actions become odd: they rarely leave the Cuddledown house, avoid the grown-ups, and give her vague riddles instead of straight answers.

The gaps in We Were Liars aren't spooky clues; they reflect psychology. Cadence is so tightly wound that each chat with the Liars nudges her to confront her past. They only reveal facts when she can listen calmly. They seem real only when she is ready to remember, not due to a ghostly force. Clinicians might call it dissociative amnesia with hallucinatory echoes of trauma.

Ghosts or grief-fueled apparitions?

Many readers of We Were Liars believe the Liars are actual ghosts. Cadence treats them as real people; they enter her summer, joking, arguing, nudging furniture, and tugging at her heart like living cousins. Their quirks- laughter, sarcasm, loyalty—perfectly mirror Cadence's memories, buzzing with life instead of eerie silence. So why not imagine them drifting through the trees as island ghosts?

The book keeps its biggest mystery deliberately vague. Lockhart never lays out clear ground rules for how the figures appear. Some fans seize on the characters' hazy, fading presence- they disappear the instant the full truth comes out as evidence that they are ghosts. Yet that interpretation rests on only half the clues.

What if they are actually lost sorrow, given a fleeting form, sadness so intense it briefly animates old, tender memories? Many people who mourn swear they see or hear someone they have lost during a dream or even a quiet afternoon. In that light, the boundary between ghost and daydream proves to be more about feeling than hard science.

A metaphorical reading of We Were Liars: The Liars as memory

Another interesting way to interpret the Liars is as metaphors rather than actual ghosts or hallucinations, representing Cadence's fractured memory and the difficult self-talk she has been avoiding. From this perspective, the Liars are not real in any practical or spooky sense. They symbolize the cousins frozen in her mind before the accident, the ones death never reached, and encountering them is the only path she has left if she hopes to heal.

The book's dreamy, almost fairytale frame aligns perfectly with this interpretation. Interspersed throughout the story are retellings of old tales, each twist rewritten to reflect how Cadence feels at that moment. The Liars also fit within this frame. To Cadence, they are characters in her private narrative—a story that must unravel before she can confront what really happened. When they fade away at the end, it signifies more than just a major reveal; it grants her the freedom to move on.

Conclusion: Ambiguity as a narrative strength

So, are the Liars ghosts, hallucinations, or something else entirely? The simplest idea is that they are psychological shadows born from trauma, guilt, and tender memories we refuse to forget. Yet, E. Lockhart plays with that notion, mixing reality and metaphor until the line blurs and readers must choose for themselves. Whether you decide they are phantoms, daydreams, or broken fragments of the past, their presence drives the book's deepest ache.

In We Were Liars, the haunting is entirely human grief that demands recognition and regret that refuses to look away. That is why the book's final twist lingers with you; it carries the weight of a secret you never wanted to uncover.
