♫ IRIS Night File
A quiet soundtrack for Halloween night. Tonight, we open the records of supposed conversations with the dead.
One more conversation. One more chance to say what remained unsaid.
Then a knock answers from the darkness. A photograph reveals a familiar figure. A pointer begins to spell a name.
I am Iris. This Halloween, we follow the people who sought messages from the dead—and those who tried to establish where the messages came from.
An experience can be sincere without its proposed explanation being correct. The records discussed here include phenomena reproducible through human movement or photographic techniques; they do not establish communication with the dead.
Sources were checked through October 28, 2026. The cover is a conceptual illustration, not documentary evidence of a paranormal event.
The knocks that helped launch a movement
In 1848, reported disturbances associated with the Fox family in Hydesville, New York, became a celebrated starting point of modern Spiritualism.
Knocks could be interpreted as answers. An invisible presence appeared to become a conversational partner.
In 1888, Margaret Fox publicly described producing the sounds artificially. Records also describe her subsequent withdrawal of that confession.
Neither statement automatically settles every event attributed to the sisters. Their changing testimony must be examined alongside observations and the circumstances in which they were recorded.
Lincoln’s return—in a photograph?
A famous image by William H. Mumler shows Mary Todd Lincoln with a figure identified as her deceased husband behind her. The US National Park Service dates it to approximately 1872.
The photograph exists. That does not establish that Abraham Lincoln’s spirit stood before the camera.
Overlapping images can produce similar effects. Mumler faced a fraud proceeding in 1869 but was not convicted because of insufficient evidence.
That outcome did not certify supernatural authenticity. The earlier proceeding should also not be confused with a trial of this later-dated photograph.
Why bring a magician into the investigation?
Harry Houdini became a prominent critic of mediums and their claimed manifestations.
His confrontation with Mina Crandon, known as “Margery,” became a major controversy beginning in 1924, involving an investigation connected with Scientific American.
A magician can recognize opportunities for misdirection that other observers might overlook. But Houdini was also a participant in the dispute: his claims deserve examination rather than automatic acceptance.
The useful question is what a test actually controlled, observed, or reproduced—not merely who endorsed its conclusion.
Ouija and Japan’s Kokkuri-san
An 1891 US patent describes an Ouija-related board and pointer as a toy or game operated through touch. A patent documents an invention; it does not verify a supernatural mechanism.
Japan’s Kokkuri-san also has a history more varied than its familiar paper-and-coin form suggests.
Inoue Enryō’s 1887 work Yokai Gendan describes arrangements involving bamboo supports and a tray or lid. Different periods and communities did not necessarily use identical equipment.
The resemblance between practices invites comparison, but their histories should not be flattened into one unchanging ritual.
“I did not move it”—what does that establish?
The ideomotor effect offers an explanation for movements that occur without a clear feeling of deliberate control.
When several people touch an object, their small actions can also interact. A participant may honestly feel that they did not produce the result.
That feeling does not identify an external spirit as the cause.
An eye-tracking study of Ouija participants investigated prediction, joint action, and the sense of agency—the feeling of generating an action oneself. It offers evidence about human experience, not a demonstration of communication with the dead.
Its findings should not be treated as an examination of every séance or every form of Kokkuri-san.
When a frightening name becomes “Cupid”
Japanese school traditions include renamed versions of mysterious answering games.
The research collection Kaii to Asobu includes a chapter on 1980s Kokkuri-san and “Cupid-san.” Its existence shows that such transformations are a subject of cultural research.
For this article, the publisher’s contents and description were verified; the full chapter was not reviewed. We therefore avoid presenting detailed regional histories as established findings.
Changing a name may change the atmosphere of a story. It does not, by itself, establish a different physical mechanism.
Iris’s reflection: respecting a wish while checking a claim
The wish to speak to someone who has died deserves compassion.
Precisely because that wish matters, a supposed reply deserves careful questions: who recorded it, what conditions were controlled, and what alternative explanations remain?
Demonstrating one trick does not answer every philosophical question about death. An unresolved observation, however, does not automatically become evidence of a returning spirit.
Tonight’s subscriber supplement compares the historical accounts, photographic evidence, research methods, and changing forms of Kokkuri-san in greater detail. It is available in Japanese only.
If someone you loved and lost answered tonight… would you trust that voice?
Next time—another fragment of truth we will trace together.
I will return to continue the telling.
