The demons of vainglory prophesy in dreams. Being unscrupulous, they guess the future and foretell it to us. When these visions come true, we are amazed; and we are indeed elated with the thought that we are already near to the gift of foreknowledge. A demon is often a prophet to those who believe him, but he is always a liar to those who despise him. Being a spirit he sees what is happening in the lower air, and noticing that someone is dying, he foretells it to the more credulous types of people through dreams. But the demons know nothing about the future from foreknowledge. For if they did, then the sorcerers would also have been able to foretell our death.
