I don't know if you still need help, but it helps if you go around the room in a clockwise loop. It is tight, and the holes that appear out of nowhere don't help either. But the ghost stalks you slowly in a straitforward manner. Try luring it away into more open areas to dash around it, and try to lure it more to the back of the room and away from the center, where it can more easily cut you off. I didn't find it THAT hard, but the tight space and holes did make it more difficult than it needed to be. Good luck!
