4. On the 1st of November, Old Celtic peoples celebrated the festival of Samhain, which marked the beginning of winter and the Celtic New Year （ just like our Spring Festival ）.

5. on October 31st, the spirits of the died would come back and move freely looking for living bodies to possess

6. Afraid of evil spirits, the living dressed up in freaky, scary costumes

7. They made a big ruckus around the neighborhood hoping that the ghosts would leave in peace before midnight of the new year

8. Some would also go from house to house, begging for "soul cakes". In return they promised to pray for dead members of the donors' families. That's the origin of trick or treat.

9. Pumpkin lanterns is necessary too. (another name is Jack-o'-lantern )

10. eventually the belief in the spirit world died down and dressing up like witches and ghoulish figures became more of a ceremony
