In the main we may conclude thus much, that those that have clear and pleasant dreams, and are not troubled with any frightful, strange, vicious, or irregular apparitions in their sleep, may assure themselves that they have some indications and dawnings of proficiency; whereas, on the contrary, those dreams which are mixed with any pain, fear, cowardly aversions from good, childish exultation, or silly grief, so that they are both frightful and unaccountable, are like the breaking waves or the billows of the sea; for the soul, not having attained a perfect evenness of temper, but being under the formation of laws and precepts from whose guidance and discovery it is free in time of sleep, is then slacked from its usual intenseness, and laid open to all passions whatever.

Whether this temper we speak of be an argument of proficiency, or an indication of some other habit which has taken deep root in the soul, grown strong and immovable by all the power of reason, I leave to you to consider and determine.
