The vardøger, vardøgr or varsel is a spirit predecessor, from Scandinavian folklore. Stories typically include instances that are nearly déjà vu in substance, but in reverse, where a spirit with the subject's footsteps, voice, scent, or appearance and overall demeanor precedes them in a location or activity, resulting in witnesses believing they've seen or heard the actual person before the person physically arrives. This bears a subtle difference from a doppelgänger, with a less sinister connotation. It has been likened to being a phantom double, or form of bilocation.
