Towards the end of the 20th century, a number of people have begun to describe themselves as elves, usually more of the Tolkien than the folkloric Santa type. Many of these people can be found in the Otherkin subculture.
Tad Williams's Memory, Sorrow, and Thorn trilogy focuses heavily on a long-lived, fair-skinned, magical race known as the Sithi, which are described as elves in all but name.
Before they became diminutive and whimsical, elves were probably akin to powerful pre-Christian forest spirits like the woodwose, the Green Man, and the drusi in the mythology of the Gauls beings to be respected and even feared. A trace of the former importance of elves in Germanic culture exists in names like Alfred (Old English lfrd, "elf-counsel") and Alvin (Old English lfwine, "elf-friend").The Scandinavian elves were of human size, which allowed "normal" human interactions: for example, in Hrlf Kraki's saga, the Danish king Helgi finds an elf-woman on an island and rapes her. Famous men could be elevated to the rank of elves after death, and in one such case, the full-sized smith hero Vlund is called an elf.What remained of the belief in elves in German folklore was that they were mischievous pranksters that could cause disease to cattle and people, and bring bad dreams to sleepers. The German word for nightmare, Albtraum, means "elf dream". The archaic form Albdruck means "elf pressure"; it was believed that nightmares are a result of an elf sitting on the dreamer's chest.
