Today it mostly compares with the modern perception of ghosts, most often being ethereal in form, and non-violent in nature. The word gjenganger is being used less, the contemporary word ghost (spøkelse) having mostly taken over. Where the term gjenganger does occur, it may be treated simply as a synonym for ghost. The corresponding verbal phrase walk again (gå igjen) is just one way of saying "haunt" with reference to ghosts.
