Most people consider that Halloween is a Chrstian Festival on October 31 celebrating Hallow's day.
What started out as a religious festival where the dead are remembered has today degenerated (at least in America) to a time when kids dress up in ever more elaborate ghoulish costumes, and movie studios get in the mood by releasing seasonal horror film titles.
To bring things back to a happier moment I would suggest:
A visit to your local Church
They are beautiful places, and you can cetainly admire the architecuture and splendor even if you might think that the underpinning religious angle is well, completely crazy.
Watch a Nice Horror Film
Remember People and Times Past from your family
A lifetimes past.
