Editing Draugr (section)

=== Shape-shifting ===
The undead Víga-Hrappr Sumarliðason of ''[[Laxdaela saga]]'', unlike the typical guardian of a treasure hoard, does not stay put in his burial place but roams around his farmstead of Hrappstaðir, menacing the living.{{sfnp|Ármann Jakobsson|2011|p=290}} Víga-Hrappr's ghost, it has been suggested, was capable of transforming into the seal with human-like eyes which appeared before Þorsteinn svarti/surt (Thorsteinn the Black) sailing by ship, and was responsible for the sinking of the vessel to prevent the family from reaching Hrappstaðir.<ref>{{harvp|Magnusson|Pálsson (trr.)|1969}}, ''Laxdaela Saga'', Ch. 18, pp. 79–80; introduction, p. 12; index of names, [https://books.google.com/books?id=um91wPf9c7MC&pg=PA255 p. 255]</ref> The ability to shape-shift has been ascribed to Icelandic ghosts generally, particularly into the shape of a seal.<ref>{{harvp|Magnusson|Pálsson (trr.)|1969}}, p.78, n1</ref>{{sfnp|Keyworth|2007|p=71}}{{sfnp|Caciola|1996|p=33, n102}}

A draugr in Icelandic folktales collected in the modern age can also change into a great flayed bull, a grey horse with a broken back but no ears or tail, and a cat that would sit upon a sleeper's chest and grow steadily heavier until their victim suffocated.<ref name="JS166">{{cite book|author=Jón Árnason |author-link=Jón Árnason (author) |editor-last=Simpson |editor-first=Jacqueline |editor-link=Jacqueline Simpson |title=Icelandic Folktales and Legends |publisher=University of California Press |year=1972 |page=166 |url=https://books.google.com/books?id=HY-DCKd6UgUC |isbn=978-0-520-02116-7}}</ref>
