Resurrection Madness

In Barovia, the souls of the dead are as trapped as the souls of the living. They become caught in the mists and can’t travel to the afterlife.
  When a humanoid who has been dead for at least 24 hours returns to life, either by way of a spell or some supernatural means, it gains a random form of indefinite madness brought on by the realization that its spirit is trapped in Barovia, likely forever. To determine how this madness is expressed, roll on the Indefinite Madness table in chapter 8 of the Dungeon Master’s Guide.
