4. Halloween is known by various names, including All Hallows’ Eve, Witches Night, Lamswool Snap-Apple Night, Samhain and Summer’s End.

5. Famous magician Harry Houdini, born in 1874, eerily died on Halloween night in 1926. He suffered from appendicitis after he suffered three stomach punches. Creepy, right?

6. Trick-or-treaters would rather get chocolate for Halloween instead of candy.

12. Halloween has been celebrated for more than 6,000 years.

13. The origin of the word “witch” means “wise woman.” It was derived from the Old English word wicce.
