What is an example of foreshadowing in "Romeo and Juliet"?

Foreshadowing In "Romeo and Juliet" is seen in Act III, scene 5 with Juliet's words, "Methinks I see thee, now thou art so low, / As one dead in the bottom of a tomb." She indeed soon sees Romeo dead.

In this scene, Romeo has just spent the night with Juliet prior to leaving for his exile to Mantua. Both young people are distraught at their impending separation and try to stall as long as possible. When Romeo starts to depart from Juliet's room, she tells him that her "ill-divining soul" is responsible for this vision of Romeo dead in a tomb. Not many hours pass before her words come true, and she awakens in the tomb to find Romeo dead.
