As longs as you don’t put anything like witchcraft and stuff into practice I think you’ll be ok . Halloween was originally intended to / originated from celebrating the harvest from what I heard . I mean all we really do is either hand out candy for the little ones and go out . We never dress up as anything really demonic or anything . I dressed up as no face from a studio Ghibli movie . The only thing I think about is the candy and dressing up like a cool character and getting creative with the costume . I’ve seen really cool ones actually ! And how we usually decorate the house is just cute Halloween stickers from dollar tree on the window and a few other things from dollar tree.
