Like many holidays, there are a series of beliefs and superstitions that surround Halloween. While it is often celebrated by kids dressing up in costumes and shoveling in way too much candy, the holiday has roots in ancient folklore and Celtic rituals. For this, Halloween is seen as an eerie holiday filled with fear–as well as mystery and magic. Halloween is also often associated with some seemingly spooky iconic animals –spiders, black cats, ravens, wolves and bats. But are they really all that spooky? Decide for yourself.
