Judges 7:3

³ Now therefore proclaim in the ears of the people, saying, 'Whoever is fearful and trembling, let him return and depart from Mount Gilead.'" Twenty-two thousand of the people returned, and ten thousand remained.

Dream

In Genesis 28:12, this signifies foresight – for prophetic dreams were predictions of things to come. (Arcana Coelestia 3698)

A dream, as in Genesis 20:3, signifies something being somewhat obscure.
