dream

\ \ [13] Old English had a word drēam, which meant ‘joy, merrymaking, music’, but it is not at all clear that this is the same word as modern English dream (the recorded Old English words for ‘dream’ were swefn and mǣting). Semantically, the two are quite a long way apart, and on balance it seems more likely that Old English had a homonym *drēam ‘dream’, which has not survived in the written records, and which was perhaps subsequently reinforced by Old Norse draumr. Both these and the related German traum and Dutch droom have been traced back to an Indo-European base denoting ‘deception’, represented also in Sanskrit druh- ‘seek to harm’ and Avestan (a dialect of Old Iranian) druz- ‘lie, deceive’.
