dream

Origin

From Middle English dream, dreem, dreeme, drem, dreme, dræm, from Old English drēam, drēm, drīm (“joy; melody, music; frenzy”), from Proto-West Germanic *draum, from Proto-Germanic *draumaz (“dream”), from earlier *draugmaz, from Proto-Indo-European *dʰrowgʰ-mos, from *dʰrewgʰ- (“to deceive”). The sense of "dream", though not attested in Old English, may still have been present (compare Old Saxon drōm (“bustle, revelry, jubilation", also "dream”)), and was undoubtedly reinforced later in Middle English by Old Norse draumr (“dream”), from same Proto-Germanic root.
