What is it called when you have weird dreams?

Answer 1

When you have weird dreams it is called, "having weird dreams." There is no particular word in the English language for weird dreams. But "nightmares" are frightening dreams, and "febrile" dreams are the distorted dreams experienced when sick with fever. "Delirium" also refers to mental delusion resulting from fever, illness or withdrawal from an addictive substance. There also are countless idioms and metaphors that refer to different sorts of dreams, including dreams that are influenced by drugs, such as pipe dreams, smoke dreams, tripping out, etc. "Hallucinations" and "delusions" generally refer to distortions one perceives while awake rather than asleep, although the terms are used of both states.
