” I Dreamt my lady came and found me dead…And breath’d such life with kisses in my lips
That i reviv’d an emperor”
romeos dream explains the future events and that juliet, once awakened would find romeo but with kisses on his lips gives him peace, and when they are both dead, they are reviv’d to be together at last. so without knowing it, romeo explains his fate, and is giving us another hint.
I think the word emperor isn’t such as literal but is used to describe his feeling to be with juliet again in the afterlife and being reviv’d isn’t coming back to life literally, but death gives him his afterlife, to be with juliet. if that makes sense…
