Whether divination by dreams is unlawful?

❌ Objection 1 : It would seem that divination by dreams is not unlawful. It is not unlawful to make use of divine instruction. Now men are instructed by God in dreams, for it is written (Job 33:15,16): "By a dream in a vision by night, when deep sleep falleth upon men, and they are sleeping in their beds, then He," God to wit, "openeth the ears of men, and teaching instructeth them in what they are to learn." Therefore it is not unlawful to make use of divination by dreams.

❌ Objection 2 : Further, those who interpret dreams, properly speaking, make use of divination by dreams. Now we read of holy men interpreting dreams: thus Joseph interpreted the dreams of Pharaoh's butler and of his chief baker (Gn. 40), and Daniel interpreted the dream of the king of Babylon (Dan. 2,4). Therefore divination by dreams is not unlawful.

❌ Objection 3 : Further, it is unreasonable to deny the common experiences of men. Now it is the experience of all that dreams are significative of the future. Therefore it is useless to deny the efficacy of dreams for the purpose of divination, and it is lawful to listen to them.
