THE huge eerie hospital building has stood empty for more than a decade after the catastrophic Hurricane Katrina in 2005 damaged the building. So the sight of Christmas tree lights mysteriously appearing in just one of its hundreds of rooms high up near the top floor sent shivers down the spines of residents overlooking the derelict Charity Hospital in New Orleans.After the haunting image was posted on social media it sparked a huge debate as to whether it was the work of the paranormal.Some suspected the vast hospital site may be haunted by many of the people who died there and that they may have been looking to brighten up life in the afterlife over the festive period.Others, of course, considered, it a digitally edited hoax.
