A pumpkin charm is used to ward away evil spirits, a witch charm honors the spirit of our ancestors, black cats – once thought evil, are now viewed as familiars who support and assist, the fangs and bat charms are to protect against vampires due to their aversion to silver, the skulls and skeletons are to remind us the power of our own humanity, and the spiders (if seen on Halloween night) means the spirit of a dead loved one is watching over you.
