Old English drēam
Middle English drem
English dream
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.

more details
The derivation from Old English drēam is controversial, since the word itself is only attested in writing in its meaning of “joy, mirth, musical sound”. Possibly there was a separate word drēam meaning “images seen while sleeping”, which was avoided in literature due to potential confusion with the “joy” sense. Otherwise, the modern sense must have been borrowed from another Germanic language, most probably Old Norse. Since this is the common sense in all Germanic languages outside the British isles, a spontaneous development from “joy, mirth” to “dream” in Middle English is hardly conceivable. In Old Saxon, the cognate drōm did mean “dream”, but was a rare word.
Attested words for “sleeping vision” in Old English, both of which appeared in The Dream of the Rood, were mǣting (Middle English mæte, mete), from an unclear source, and swefn (Modern English sweven), from Proto-Germanic *swefnaz, from Proto-Indo-European *swepno-, *swep-; compare Ancient Greek ὕπνος (húpnos, “sleep”).
