Make offerings at the temples of the travel gods, hold onto your talismans, wear your shirt inside out and carry a hazel stick.
Don't got into the woods after dark.
Do not acknowledge cute little old ladies, beautiful women or lost children. Do not heed the weeping in the trees, or the laughter, or the cries for help. Do not follow the swaying of lanterns in the darkness. If your friend left the path, they are gone. That is not their voice you hear.
But most of all don't go into the woods after dark.
