A census of the claims
Every dossier is tagged with the classes of phenomenon its claims and legends file under — apparition, phantom music, curse, lights. 187distinct classes cover 3,886 filings across 2,569 dossiers. The distribution is not remotely even, and the tail is longer than the head is tall.
The thirty most filed classes
dossiers carrying each6 classes filed a hundred times or more account for 3,091 filings — 79.5% of the total. 164 of the 187 classes were filed fewer than ten times.
Classes that travel together
1,195 dossiers file under two or more classes — the deepest carries 5. The pairing that appears most is no surprise: a named ghost and the thing witnesses report seeing are the same haunting described twice.
What a filing measures
A filing is a vocabulary event: at least one claim or legend in the dossier was classed under that label. It measures what the record says, not what happened — a place famous enough to attract ten write-ups can file the same class ten ways, while a one-source legend files it once. Counts rank documentation, not credibility.
The tail is the honest part. 88 classes — 47.1% of the entire vocabulary — were filed exactly once: ufo sightings, folklore creatures, tragic lovers legend, transformation legend, and 84 more. Most are classification orphans — a tradition a source named and no second file ever needed — but each still holds a dossier that nothing else in the archive describes quite the same way.
And the pairings are not sightings stacking up. When apparition and named ghost legend share a file 663 times, that is the record writing the same ghost down twice — once as the thing seen, once as the name attached. Co-occurrence measures how the archive describes a haunting, not how haunted the place is.
