[2026 Latest] Top 3 Ranking of Paranormal Rumors at Dams and Coastlines
Dams and coastlines present different dangers, including management facilities, water levels, waves, and cliffs. Official documents deal with facilities, nature, and public access conditions, not proof of paranormal phenomena.
*The illustrations in this text are AI-generated horror illustrations based on each location.
The premise of this article
Don't make decisions based on rumors alone.
The rankings in this article do not indicate the existence or degree of terror of the paranormal phenomena. Facts verifiable from official sources, rumors without verifiable sources, and current safety/visiting information are placed in separate sections so that readers can return to the original sources.
Return to official documents
Anything not mentioned on the official website is neither confirmed nor disproven based on personal experience. In this article, anything marked "unconfirmed" will not be included, and no accidents, numbers, strange occurrences, or causal relationships not found in primary sources will be added.
How to read rankings
Meaning of 5 axes and 100 points
We score based on the following criteria: source transparency (30), historical/spatial context (25), safety information (20), recency of publicly available information (15), and source transparency of rumors (10). This is not a score for fear level or danger level.
4-value classification
The relationship between official documents and rumors will be recorded using one of four values: "match," "partially match," "mismatch," or "unconfirmed." For each location, the facts that matched, the points that could not be confirmed, the newly confirmed facts, and the final judgment will be written individually.
Protecting things on-site
Do not enter private property, closed areas, areas inside fences, or unmanaged areas at night. Do not engage in dangerous activities for the purpose of photography or daredevil, and prioritize the latest information from the administrator or local government.

What we can learn from the comparison
While the existence and background of all three locations can be officially confirmed, the core of the supernatural phenomenon remains unconfirmed. Historical facts and the fact that the details of the rumors are true are two different things.
Handling during updates
If new municipal documents, administrator information, or corrections are found, the date of confirmation, URL, and changes will be recorded and re-evaluated. Avoiding disruptive consumption of quiet spaces is also included in the quality of the article.
FAQ
Is this ranking proof of paranormal activity?
No. I'm comparing whether we can go back to official sources and how well we can verify the rumors.
If it's not written in the official documents, does that mean it's a lie? No. Anything not mentioned will be marked as "unconfirmed" to avoid making a definitive statement.
Is it okay if I come at night? We do not recommend this. Please respect the opening hours, traffic restrictions, and signs indicating private property and closed areas.
