 To say he [God] hath spoken to him in a dream is no more than to say that he dreamed God spake to him, which is not of force to win belief from any man that knows dreams are for the most part natural and may proceed from former thoughts … To say he hath seen a vision, or heard a voice, is to say that he hath dreamed between sleeping and waking; for in such a manner a man doth many times naturally take his dream for a vision, as not having well observed his own slumbering (Hobbes 1651, 32.6)
