Ghostly images have been seen coming and going in an unusually frequent number near the corner of Doray Drive and Contra Costa Boulevard in Pleasant Hill recently. The unusual sightings are expected to subside later in the week after children made their annual rounds on Halloween night, dressed as ghosts, goblins, witches and other costumed characters.
