Just to clarify what someone wrote, no pagan that I know "worships" the dead. There are so many lies and misconceptions about pagans because of what people are programmed into believing by churches including JWs. Nor do they worship the devil. A very minute sub-culture, called Satanists, believe in Satan. The rest don't even believe in him, he is a construct of Jewish/Christian theology.
On Samhain, pagans believe that the veils are thin between the world we live in, and the spirit world, or the summerland. At that time, oftentimes you can feel closer to a deceased loved one, or some claim to talk to them, I've never known anyone who did, but I know there are those that do. There is no worship involved, but there is honor. Its kind of a combined holiday for pagans, half Pagan new year, because the circle of the year begins in the fall for us, and its half akin to Memorial Day although we are remembering all lost loved ones and ancestors and not just military.
I'm only trying to communicate some of this to you all, not all of it is my own, but I nevertheless expect to be flamed.
