"The distinction between a vision and a dream is no small one... A dream differs from a vision in that the one is indicative of what is to come, and the other of what is. ...It is the nature of experiences to return during sleep and re-present themselves to the soul, thus creating dream manifestations... [B]ody-related dreams arise from lack or excess, soul-related from fear or hope. ...[A] dream operates as a vision calling attention to a prediction of what is to come, and after sleep it... tends to rouse and impel the soul to active undertakings..."
