Andrea Haugen (born Andréa Meyer; 6 July 1969 – 13 October 2021), also known under her artist names of Aghast, Hagalaz' Runedance, Andréa Nebel, Nebel and Nebelhexë, was a German musician, model and author.

Haugen worked as a model in London, but soon rejected it as a "shallow scene".

[2] Haugen cited her influences as the Cocteau Twins, Kate Bush, and The Benedictine Monks of Santo Domingo de Silos.

[citation needed] She released her first music as Aghast in 1995, then from 1996 to 2002 under the name Hagalaz' Runedance.

[3][6] In 2012 she expressed frustration at some journalists' misconstruing song lyrics of hers as being about "witches in the wood, Nazism, nature, or pollution of the environment" when they were "relatively clearly" about "incest, a friend's suicide, child abuse, or loneliness".
