What is Halloween based off of?
Samhain, pronouced "sowain". It is a pagan holiday when the souls can bridge between the living and the spirit worlds.
It's a long story but it started as a catholic holiday where people would go "trick or treating" for soul cakes for each one the got they would pray for people in purgatory
Long story short,it's based off of people killing others and dressing up in there skin.Its a horrifying reason to hide from the spirits they believed that existed
Some pagan ritual. Nothing important.
