An expert in the study of paranormal events from Charles Sturt University (CSU) believes the only scary thing about Halloween is the risk of tooth decay from all the sweets that children have an excuse to guzzle on the day. Dr Krissy Wilson, Head of CSU’s Science of Anomalistic Phenomena research unit, said the celebration of Halloween most likely started as a pagan tradition that coincided with the new harvest. “It later became a Christian celebration of All Hallows or All Saints Day. Modern times have seen it evolve into ‘Halloween’ – which came literally from ‘hallowed’ or ‘holy’ – that typically involves trick or treating, dressing up in silly outfits and watching horror movies!”
