Richter 7:10

¹⁰ Fürchtest du dich aber hinabzugehen, so laß deinen Diener Pura mit dir hinabgehen zum Lager,

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.

³ But God came to Abimelech in a dream of the night, and said to him, "Behold, you are a dead man, because of the woman whom you have taken. For she is a man's wife."
