Many of the customs of Halloween today are based on beliefs and customs
of long ago. It was common in many old cultures of Europe and other
parts of the world to celebrate an autumn holiday each year.
The favorite time to celebrate this autumn holiday was at the end of
October. The date marked the end of summer and the harvest season and
the beginning of the cold, dark winter.
On that last night in October it was believed that the dead could return
to the world of the living. In their return, the dead would take the form of ugly witches,
scary ghosts, creepy goblins or some other strange creature. These
creatures of the underworld would then join in a festival of the wicked
where they played mean tricks and caused all sorts of trouble in the
villages and fields.
