Why is Halloween celebrated?
Historically, Halloween has been more about remembering those who have passed on rather than playing dress up.
It's rooted in the ancient Celtic festival of Samhain where the souls of the dead were believed to return to visit their homes.
The modern tradition of dressing as ghosts and ghouls is rooted in a Samhain practise where people would sometimes wear masks and other disguises in order to avoid the ghosts thought to be present.
While Halloween originated in Europe, the custom came to America in the 1840s with the arrival of Irish immigrants.
