Your Authours opinion, concerning Dreams,[1] seemeth to me in some part very rational and probable, in some part not; For when he sayes, that _Dreams are onely Imaginations of them that sleep, which imaginations have been before either totally or by parcels in the Sense; and that the organs of Sense, as the Brain and the Nerves, being benumb'd in sleep, as not easily to be moved by external objects, those Imaginations proceed onely from the agitation of the inward parts of mans body, which for the connexion they have with the Brain, and other organs, when they be distemper'd, do keep the same in motion, whereby the Imaginations there formerly made, appear as if a man were waking_; This seems to my Reason not very probable: For, first, Dreams are not absolutely Imaginations, except we do call all Motions and Actions of the Sensitive and Rational Matter, Imaginations. Neither is it necessary, that all Imaginations must have been before either totally or by parcels in the Sense; neither is there any benumbing of the organs of Sense in sleep. But Dreams, according to my opinion, are made by the Sensitive and Rational Corporeal Motions, by figuring several objects, as awake; onely the difference is, that the Sensitive motions in Dreams work by rote and on the inside of the Sensitive organs, when as awake they work according to the patterns of outward objects, and exteriously or on the outside of the sensitive Organs, so that sleep or dreams are nothing else but an alteration of motions, from moving exteriously to move interiously, and from working after a Pattern to work by rote: I do not say that the body is without all exterior motions, when asleep, as breathing and beating of the Pulse (although these motions are rather interior then exterior,) but that onely the sensitive organs are outwardly shut, so as not to receive the patterns of outward Objects, nevertheless the sensitive Motions do not cease from moving inwardly; or on the inside of the sensitive Organs; But the rational matter doth often, as awake, so asleep or in dreams, make such figures, as the sensitive did never make either from outward objects, or of its own accord; for the sensitive hath sometimes liberty to work without Objects, but the Rational much more, which is not bound either to the patterns of Exterior objects, or of the sensitive voluntary Figures. Wherefore it is not divers distempers, as your Authour sayes, that cause different Dreams, or Gold, or Heat; neither are Dreams the reverse of our waking Imaginations, nor all the Figures in Dreams are not made with their heels up, and their heads downwards, though some are; but this error or irregularity proceeds from want of exterior Objects or Patterns, and by reason the sensitive Motions work by rote; neither are the Motions reverse, because they work inwardly asleep, and outwardly awake, for Mad-men awake see several Figures without Objects. In short, sleeping and waking, is somewhat after that manner, when men
