3181. CONCERNING DREAMS, HOW AND BY WHOM THEY ARE PRODUCED. ((((I have learned by much experience, how dreams are produced, and what spirits produce them. When in a state of wakefulness, and when another [was] in a state of sleep, or in sleep, I was then as it were a spirit in company with spirits: and thus it was granted to me to be present with those spirits who introduce dreams, and it was also granted me to introduce dreams; and that it was so I have learned from experience, inasmuch as another waked up, three or four times, after dreams were introduced by me, and I then related the things [of his dream] which he acknowledged. It was granted me to introduce such things as were delightful and pleasant. I was then instructed by living experience, who they were that introduced dreams and how. It occurred by means of representations, for the end that the sleeper might be delighted, and there are those whose office it is to watch over man, when he sleeps, that he may not be infested by evil spirits. They discharge this office in wakefulness with the greatest delight, so that they strive [aemulentur] which of them may be present; and because they are good spirits, they love those things which are most pleasant and delightful to those [asleep].))))
