Heck, EVERY day was Halloween on DS!
Yes, every day was Halloween in Collinsport until...
One day, Barnabas caught David as he was falling out of a tree, and saved David from breaking his leg, or his neck, or his something.
David, inspired, ran off and lit Julia's cigarette for her, and told her to Pay It Forward.
Julia went and hypnotized Mrs. Johnson so that she would never feel any back pain again, and told Mrs. Johnson to Pay It Forward.
Mrs. Johnson grumbled a lot, but dutifully took her life savings out of the Collinsport National Bank and gave them to Maggie Evans so Maggie could fulfill her lifelong dream of going to Paris. She told Maggie, "Just Pay It Forward. Don't ask me why."
Before she left for Paris, Maggie came across Sheriff Patterson, stuck in the middle of nowhere with a flat tire, so she changed his tire for him. [Why oh why does that sound like a euphemism for something else?]
And so on and so forth, until finally everybody in Collinsport had done a good deed for somebody else, and the next day....
IT SNOWED! And it was November 1, and no supernatural events ever happened in Collinsport again.
