Festival culture: Halloween originated from celebrations related to evil spirits, so witches, ghosts, goblins and skeletons riding brooms are all symbols of Halloween. Bats, owls and other nocturnal animals are also common symbols of Halloween. At first, these animals were terrible because people thought they could communicate with the ghosts of the dead. The black cat is also a symbol of Halloween, and it also has a certain religious origin. People believe that black cats can be reincarnated and have the ability to predict the future. In the Middle Ages, people thought that witches could become black cats, so when people saw black cats, they thought that witches were pretending. These marks are common choices for Halloween costumes and common decorations on greeting cards or windows.
