ROMEO: I dream’d a dream to-night.
MERCUTIO: And so did I.
ROMEO: What was yours?
MERCUTIO: Dreamers often lie.
ROMEO: In bed asleep, while they do dream things true.
– William Shakespeare
Romeo and Juliet, Act 1, Scene 4. Romeo and Mercutio engage in banter about dreams as they walk through the streets on the way to the Capulets’ household. The skeptical Mercutio mockingly says of Romeo’s dreaming, that people who dream often lie. Romeo quickly retorts with a pun that they lie in bed asleep, as they dreams true things.
