Gjenganger

A gjenganger is a type of ghost from Scandinavian folklore. It's like a person who has died but keeps coming back to life and won't stay dead.

Imagine you're playing a game of tag and your friend keeps tagging you over and over again, even though you've already been caught. That's what a gjenganger does - it keeps coming back, even though it's supposed to be dead.

But instead of being scary like a monster, gjengangers are usually just sad and lonely. They're stuck in this world when they should be resting peacefully in the afterlife.

People used to think that gjengangers would try to harm the living, but really they just want to be left alone. So if you ever see a ghostly figure who looks like they don't belong in the world anymore, just let them be and don't bother them.
