And therfore, faire Pertelote so deere,
By swiche ensamples olde yet maistow leere,
That no man sholde been to recchelees
Of dremes, for I seye thee doutelees
That many a dreem ful soore is for to drede.

– Geoffrey Chaucer

The Canterbury Tales, The Nun’s Priest’s Tale. Chauntecleer tells his fair Pertelote that ancient examples he has quoted teach us that no one should be too heedless of dreams. Many a dream is something greatly to be feared, he adds.
