Hypnosis Pokémon ^#96

If you sleep by it all the time, it will sometimes show you dreams it had eaten in the past.

  This Pokémon cannot be asleep. This causes rest to fail altogether. If a Pokémon is asleep and acquires this ability, it will immediately wake up; this includes when regaining a lost ability upon leaving battle. This ability functions identically to vital spirit in battle.
