This nifty little ghost story was recorded by Jonathan Ceredig Davies in his "Folk-lore of West and Mid-Wales," 1911:
There was a farmhouse in a certain part of West Wales, in which a large and respectable family lived. But there was one room in the house haunted by a troublesome spirit which often cried out in a mournful voice, “Hir yw’r dydd, a hir yw’r nos, a hir yw aros Arawn” (long is the day, and long is the night, and long is waiting for Arawn). Things went on in this manner for a long time, and not one hardly ventured to open the door of that room. But one cold winter evening when every member of the family sat around the fire, before supper, somebody called at the door of the house, and a stranger was welcomed in to warm himself by the fire. The stranger asked for some food and a bed for the night. He was told he was welcomed of food, but that they were sorry they could not offer him a bed, as all the beds were hardly enough for themselves, and that the only spare bed-room in the house was haunted. Then the stranger begged to be allowed to sleep in that room, as he felt sure that there was nothing to do him harm there. The man appeared very tired, and spoke but little except in reply to questions, and when it was found out that his name was “Arawn,” all the family looked into each’s face in great surprise. The stranger presently went to bed in the haunted room, and strange to say everything was quiet in that room that night, that is, no spirit was heard as usual crying and moving things about. When the family got up next morning, the first thing was to find out what kind of night the stranger passed in the haunted room, but to the surprise of all the man was gone, and the ghost was also gone, for the room was never haunted afterwards.
