Ghost Myth in The Savage Woods | World Anvil

Ghost

When a person dies, their lua returns to the sea, their tausai fades away, and their panai ascends to the Forest of the Dead behind the stars.
  Sometimes, however, a panai gets lost.
  This might happen from particularly sudden or violent deaths, which cause the soul such a shock that they don't quite understand that they're dead. Other times, it happens because they died in their sleep, while their panai was wandering away from their body in dreams. If the body is moved before the panai returns, they will become lost and confused, and unable to find their way to the sea. In both cases, the panai lingers in the world as a pale, translucent image of how they were in life in the moments before their death.
  Ghosts are not dangerous. They cannot physically touch a person or interact with the world, and they only wish people harm if they were also violent in life. They are sad, confused, and despondent. They lurk on the outskirts of humanity, lingering near villages or in the edge of a campfire's light, looking on with longing. Their only danger is in unintentionally luring people into the woods to find the "person" they glimpsed wandering, in an effort to help.
  Witches try to help ghosts when they can. A witch will attempt to communicate with the ghost and guide them toward the sea, so that they can move on.
