Ghosts (original Danish title: Gengangere) is a play by the Norwegian playwright Henrik Ibsen. It was written in 1881 and first staged in 1882. Like many of Ibsen's better-known plays, Ghosts is a scathing commentary on 19th century morality.
The play was originally written in Danish. The word "Gengangere" is not Norwegian. The Norwegian word is "Gjengangere" but the translation is reasonable, literally translated as "again walkers". Norwegians also use the term about people who frequently show up in the same places, be they pubs, parties or first nights or other places or occasions.
