Somnium

Somnium, or Morph (from the Ancient Greek God of Dreams 'Morpheus') as a slang term in various human nations such as the Terran Federal Republic, is a highly-addictive sleep-inducing drug that causes the lifeform who takes the drug to have strange, but usually enjoyable, dreams. Users of the drug are sometimes called 'remmies', and falling asleep as a result of the drug is referred to as 'getting remmy'.
