Bad Dreams (Japanese: ナイトメア Nightmare) is an Ability introduced in Generation IV. It is the signature Ability of Darkrai.

Effect

In battle

At the end of each turn, each adjacent sleeping opponent takes damage equal to 1/8 of its maximum HP.

Bad Dreams inflicts damage after a Pokémon that is drowsy due to Yawn falls asleep (and thus inflicts damage to a Pokémon the same turn it falls asleep due to drowsiness). Bad Dreams applies after a Pokémon has the opportunity to be woken up by Hydration, Shed Skin, or Healer.

Outside of battle

Bad Dreams has no effect outside of battle.
