After a historical survey of work on the musical dream during the last thirty years, some theoretical issuesconcerning the relation of music and language are raised. It is observed that music, unlike language andimagery, does not undergo distortion in dream, and that in the word-music combination, music overrideswords. It is also suggested that song may be primarily a right-hemisphere function, in which music adoptsbut subordinates language, which has limited representation in the RH. The integrity of music, ascompared to language, in dream may also be related to RH dominance during sleep.
