When the Christians were trying to convert pagans, they decided to incorporate pagan festivals into Christianity. One of these festivals was Samhain (pronounced sow-in) which was a celebration of the end of the harvest and the beginning of winter.
It was said to be the time when the veil between worlds was thinnest and spirits could roam.
Bonfires were important to revitalize the earth. Some bonfires would be low enough that people could jump over them and, in some cases, two bonfires were made so that cattle could be herded between them.
It became known as "All Hallows Eve" (Since Nov. 1 was All Saints Day) and then Halloween.
***
Shadows dance upon the wall,
like they’re at a fancy ball,
lightning flashes across the sky
thunder rumbles, the time is nigh.
The clouds must break and from them must fall
a rain droplet carnival.
What better friend to wind than rain
and without them both it’s not the same.
They are invited to the party too,
guess who’s next, I dare you to -
Although the moon cannot be seen
and from the clouds she can’t be gleaned,
she is invited, the stars as well
and some more straight from hell.
Ghosts and goblins, monsters plenty
all can come to Pandemonium City
