Vidna Obmana (stylized vidnaObmana on many album covers) is a pseudonym used by Belgian composer and ambient musician Dirk Serries. The name Vidna Obmana, a phrase in Serbian, literally translates to "optical illusion" and was chosen by Serries because he felt it accurately described the music. Serries created music under the Vidna Obmana pseudonym from 1984 until 2007, when he officially retired the name. Most of his current work is released under the Fear Falls Burning pseudonym.
