Don't Celebrate-Halloween:

The October 31st holiday that we today know as Halloween has strong roots in paganism and is closely connected with worship of the Enemy of this world, Satan. It is a holiday that generally glorifies thedark things of this world, rather than the light of Jesus Christ, The Truth. Have you noticed how costumes and masks are getting generally more bloody, gory, and depraved each year? Unfortunately, the gruesome and grotesque and theoccult are increasingly glorified in American society, not only on Halloween, but throughout the year in frequent horror movies and television programs.(Christian Answers: here)
