During Halloween, time-released curses are always loosed. A time-released curse is a period that has been set aside to release demonic activity and to ensnare souls in great measure ... During this period demons are assigned against those who participate in the rituals and festivities. These demons are automatically drawn to the fetishes that open doors for them to come into the lives of human beings. For example, most of the candy sold during this season has been dedicated and prayed over by witches.
I do not buy candy during the Halloween season. Curses are sent through the tricks and treats of the innocent whether they get it by going door to door or by purchasing it from the local grocery store. The demons cannot tell the difference.
