Yes. I remember that commandment quite clearly. "Thou shalt not Trick or Treat."
You're hilarious PJ.
It most likely falls under the 1st commandment:
Exo 20:3 Thou shalt have no other gods before me.
By observing days dedicated to false gods against the wishes of God, you are putting other gods ahead of God.
From the article:
Halloween is a celebration of the opposite—of demonism, witchcraft, death and evil spirits.
God's Word makes it clear that no one should dare entertain witchcraft or act as a sorcerer. "There shall not be found among you anyone who makes his son or his daughter pass through the fire, or one who practices witchcraft, or a soothsayer, or one who interprets omens, or a sorcerer, or one who conjures spells, or a medium, or a spiritist, or one who calls up the dead. For all who do these things are an abomination to the LORD" (Deuteronomy 18:10-11, emphasis added throughout).
God pronounced death on any Israelites who would dare dally with demonism or Satanism: "A man or a woman who is a medium, or who has familiar spirits, shall surely be put to death; they shall stone them with stones. Their blood shall be upon them" (Leviticus 20:27). "You shall not permit a sorceress to live" (Exodus 22:18).
Why such a harsh penalty? God did not want such perverted, demonic practices to spread among His people and corrupt others. "But that prophet or that dreamer of dreams shall be put to death, because he has spoken in order to turn you away from the LORD your God, who brought you out of the land of Egypt and redeemed you from the house of bondage, to entice you from the way in which the LORD your God commanded you to walk. So you shall put away the evil from your midst" (Deuteronomy 13:5).
