Halloween customs, though, can be found in many other parts of the globe.

Many people, though, regard these celebrations as harmful for the following reasons:Firstly,Halloween is actually related to the prospect of contact with spiritual forces, many of which threaten or frighten.

Even today, people around the world use these days to make contact with supposed spirits of the dead. Secondly, although Halloween has been viewed mainly as an American holiday, each year people in more and more countries have been adopting it. Many newcomers to the celebration, however, are unaware of the religious origins of Halloween symbols, decorations, and customs, most of which are related to supernatural beings and supernatural forces. Thirdly, thousands of people, who follow ancient Celts(凯尔特人), still call Halloween by the ancient name Samhain and consider it to be the most sacred night of the year. Others don’t realize it, while they’re celebrating the Celtic holiday. In view of the foregoing, it is wise for you to know about the dark origins of Halloween and similar celebrations.

A. Americans
B. Canadians
C. Indians
D. Celts
