Trough bonfires, trick or treating, wearing costumes and telling stories

Explanation:

First of all, how it started? Origins of Halloween are dating since the ancient Celtic festival of Samhain.

This was the festival which was celebrated by the Celts and they celebrated New Year on the first November. Why on the first of November? Because that day was referring beginning of cold and dark winter and because of that, the harvest, end of the summer and others, it was also bounded with death. People were believing that on that eve, there is a blurred line limit between the one who lives and the ones who are dead and that is why for example why zombie, vampire, Dracula, ghosts, and other costumes are so characteristic. Some of the customs at first were including bonfires and ghost costumes and later it evolved in trick or treating. When Halloween first came to the USA, the customs were including celebrating the day of harvest and neighbors were talking scary stories, sing, and dance and Americans have borrowed trick or treating and wearing costumes from European people.
