Pseudo-Clement

It is made known that the devout as well as the impious see visions and dreams, as can be proved from Scripture.… Nebuchadnezzar, who worshiped images and ordered those who worshiped God to be cast into fire, saw a dream extending over the whole age of the world.… Thus, we cannot infer with absolute certainty that the one who has seen visions and dreams and apparitions is undoubtedly devout. For in the case of the devout person, the truth gushes up natural and pure in his mind, not worked through dreams but granted to the good through intelligence.

Nebuchadnezzar, having ordered the three men to be cast into fire, saw a fourth when he looked into the furnace and said, “I see the fourth as the Son of God.” He was impious and yet saw apparitions, visions and dreams. Thus, we cannot infer with absolute certainty that the one who has seen visions and dreams and apparitions is truly impious. To be sure, for the devout person, the truth gushes up natural and pure in his mind, and not by way of dreams.
