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.
