Nishi dak
The nishi dak are ghosts of people who weren't given a proper burial, and appear as shadows in the distance. The word nishi means 'night' and dak means 'call' – the nishi dak will choose a victim and call out to them in the voice of their loved one. They will use these calls to lure their victim into a secluded area before revealing themselves and killing their victim.
However, it's possible to distinguish between the call of the nishi dak and the voice of a loved one. The nishi dak can only call out twice, so if you hear your name announced three times, you know you aren't being haunted by a ghost.
