age of the actions of an other man; as when a
man imagins himselfe a Hercules, or an Alexander, (which happeneth often
to them that are much taken with reading of Romants) it is a compound
imagination, and properly but a Fiction of the mind. There be also other
Imaginations that rise in men, (though waking) from the great impression
made in sense; As from gazing upon the Sun, the impression leaves an
image of the Sun before our eyes a long time after; and from being long
and vehemently attent upon Geometricall Figures, a man shall in the
dark, (though awake) have the Images of Lines, and Angles before his
eyes: which kind of Fancy hath no particular name; as being a thing that
doth not commonly fall into mens discourse.

Dreams

The imaginations of them that sleep, are those we call Dreams. And these
also (as all other Imaginations) have been before, either totally, or
by parcells in the Sense. And because in sense, the Brain, and Nerves,
which are the necessary Organs of sense, are so benummed in sleep, as
not easily to be moved by the action of Externall Objects, there can
happen in sleep, no Imagination; and therefore no Dreame, but what
proceeds from the agitation of the inward parts of mans body; which
inward parts, for the connexion they have with the Brayn, and other
Organs, when they be distempered, do keep the same in motion; whereby
the Imaginations there formerly made, appeare as if a man were waking;
saving that the Organs of Sense being now benummed, so as there is
no new object, which can master and obscure them with a more vigorous
impression, a Dreame must needs be more cleare, in this silence of
sense, than are our waking thoughts. And hence it cometh to pass, that
it is a hard matter, and by many thought impossible to distinguish
exactly between Sense and Dreaming. For my part, when I consider, that
in Dreames, I do not often, nor constantly think of the same Persons,
Places, Objects, and Actions that I do waking; nor remember so long a
trayne of coherent thoughts, Dreaming, as at other times; And because
waking I often observe the absurdity of Dreames, but never dream of
the absurdities of my waking Thoughts; I am well satisfied, that being
awake, I know I dreame not; though when I dreame, I think my selfe
awake.

And seeing dreames are caused by the distemper of some of the inward
parts of the Body; divers distempers must needs cause different Dreams.
And hence it is, that lying cold breedet
