Evil Dreamer is an enemy in Final Fantasy IV: The After Years. They are dangerous foes as their Fira deals significant Fire-elemental damage to a party member, which they follow up with a powerful physical attack on their next turn, then casts Sleep on a party member, and then repeat their pattern. It is highly recommended to defeat them quickly, or inflict them with Sleep or Confusion to help reduce the amount of damage the party takes.
