寝言|ねごとnegoto[0]heiban (flat)

1. nountalking in one's sleep; somniloquy
   就寝しゅうしん中ちゅう、寝言ねごとが多おおいのです。↗

   I talk in my sleep very often.
2. no-adjectivenonsense; gibberish

• SynonymうわごとNeutralWords uttered unconsciously during a high fever or delirium; 「寝言」 is what one says while asleep, so the two differ in cause.
• Synonym譫言せんげんNeutralFiguratively the two are close: 「寝言」 leans toward impractical empty talk and twisted logic, 「うわ言」 toward incoherent nonsense.
• Synonym囈語げいごNeutralAnother writing of 「うわ言」, meaning unchanged; unlike 「寝言」 it arises from feverish delirium rather than sound sleep.

Use 「寝言」 for sleep talking, literally or figuratively for impractical empty talk. For unconscious delirious talk from high fever, and for incoherent nonsense, use 「うわ言」, also written 「譫言」 or 「囈語」.
