The Vampire Diaries told a number of ghost stories this week, as Anna bonded with Jeremy, Vicki almost murdered Elena and, oh yeah, Mason Lockwood made a shocking return. Much to the extreme dismay of Damon.

Don't look for the ghostly visits to slow down next Thursday, either.

On the aptly-titled "Ghost World," Mystic Falls will prepare to celebrate Illumination Night, only to be invaded by multiple spirits. As the following promo teases, the one whose death Damon is responsible for will especially cause problems for this blood sucker. Elsewhere, Elena will ask Jeremy to assist her with Stefan, while Alaric will discover a clue to his past.

Watch the official CW trailer now. Try not to get spooked...
