Where does the legend of the Boogie Man come from, what qualifies one as a boogie man.?

Answer 1

The bogeyman legend may originate from Scotland, where such creatures are sometimes called bogles, boggarts, or bogies.

Bogeyman tales vary by region. In some places the bogeyman is male, in others, female. In some Midwestern states of the USA the bogeyman does not enter bedrooms but instead scratches on the windows. It is said that a wart can be transmitted to someone by the bogeyman. Bogeymen may be said to target a specific mischief – for instance, a bogeyman that persecutes children who suck their thumbs – or just general misbehaviour.
