I remember hearing from other people back in the day, the story about the nurse on the motorway.
http://joegraham.rushlightmagazine.com/belfastghosts.html"At Beechmount many are the reports that one used to hear of people having seen a Headless Nun. Some reported seeing the statue of Our Lady in the grounds of St Rose’s school crying and omens such as the outbreak of the present troubles were read into the incident ... all this just a year before the troubles started."
"Another famous ghost is that of the young nurse who was killed in an accident on the Ml some years ago. Her ghost has been often given lifts by passing motorists who stopped and let her into their cars after seeing her standing at the side of the motorway. The motorists sp of reaching Belfast and on asking the girl where she wanted out, they got no answer. Looking round, to their horror, they found the back seat where the girl had been sitting empty ... she had disappeared . and yet, they hadn’t stopped since picking the girl up!"
