Read this stanza from the poem “Dreams,” by Paul Laurence Dunbar.

Which figure of speech is used in the bold line?

What dreams we have and how they fly
LIKE ROSY CLOUDS ACROSS THE SKY;
Of wealth, of fame, of sure success,
Of love that comes to cheer and bless;
And how they whither, how they fade,
The waning wealth, the jilting jade—
The fame that for a moment gleams,
Then flies forever,—dreams, ah—dreams!
