Frequently Asked Questions

What is the scariest fact about Halloween?

Many historians point to Samhain itself - the Celts genuinely believed the dead walked among the living on October 31, and the original costumes were designed to hide from real ghosts, not to win contests.

Why are black cats associated with Halloween?

In medieval Europe, black cats were believed to be witches' familiars - spiritual companions that helped witches cast spells. The superstition was so strong that black cats were sometimes burned alongside accused witches.

What were the first jack-o'-lanterns made from?

Turnips, potatoes, and beets in Ireland and Scotland. Irish immigrants switched to pumpkins after arriving in North America because pumpkins were larger and far easier to carve.
