Poltergeist Phenomenon
Derived from the German for “noisy ghost,” a poltergeist refers to a phenomenon where objects move, sounds occur, or lights flicker in a specific location. Characterized by physical force and sound, it is generally considered a type of paranormal activity. Scientifically, theories propose causes such as static electricity, infrasound, or psychological factors (often said to involve adolescents), but much remains unexplained. The phrase in the article title, “Something appeared every day. Around 3 AM, from the kitchen…” precisely aligns with a typical description of a poltergeist. For instance, rattling dishes, sounds of objects falling, or strange noises heard in an otherwise empty kitchen strongly suggest this phenomenon. In multi-unit dwellings, it's easy to mistake sounds from neighbors, creaks in the building, or plumbing noises for something else, but recurring disturbances at specific times are more likely to evoke a poltergeist interpretation. This phenomenon has been documented worldwide since ancient times and continues to captivate many as a subject of paranormal shows and urban legends.
Sound Transmission and Resonance in Multi-Unit Dwellings
In multi-unit dwellings like apartments and condos, "sound transmission"—where living noises from adjacent or upper/lower floors are unintentionally conveyed—occurs frequently. This is common not only in wooden apartments but also in reinforced concrete buildings, due to structural characteristics that allow sound to travel through walls and floors. For example, footsteps from the floor above, drainage sounds, TV noise from a neighboring room, or even subtle vibrations transmitted through electrical outlets can resonate unnaturally in the quiet of late night. Furthermore, depending on the specific building structure or room shape, "resonance phenomena" can occur, making certain frequencies of sound more likely to echo. The article's mention of “Around 3 AM, from the kitchen…” could suggest that a neighbor's routine (e.g., preparing food after a night shift or using the restroom late at night) is the cause. It's not uncommon for sounds like water flowing through pipes, boiler operation, or the contraction sounds of a building due to temperature changes to be heard only late at night. When heard in the sensitive hours of late night, these ordinary sounds can feel eerie and inexplicable, unlike their daytime counterparts. Many incidents mistaken for paranormal phenomena are, in fact, often caused by such physical acoustic phenomena.
"Ushimitsu-doki" and Human Psychology
The specific time of "3 AM" has long been known in Japan as "Ushimitsu-doki," a sinister hour when Yokai (supernatural beings) and ghosts are believed to appear. Even today, this time is shrouded in silence as most people are in deep sleep, making even small sounds seem very loud or normally unnoticed sounds eerie. Human psychology is also easily affected during this time; sleep deprivation, fatigue, and stress can heighten the senses or make one prone to auditory hallucinations and illusions. Scientifically, around 3 AM, the body temperature is at its lowest, and melatonin secretion peaks, indicating the body is in rest mode. This decrease in alertness and minimal external stimuli can amplify feelings of anxiety and fear, dulling rational judgment. Therefore, even if the "unusual occurrences from the kitchen" experienced by the article's protagonist were merely ordinary sounds, it is entirely possible that hearing them at this hour could make them feel like a supernatural phenomenon. The combination of cultural background and human physiological/psychological characteristics makes 3 AM a memorable and symbolic time for "strange things" to happen.
