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 breedeth Dreams of Feare,
and raiseth the thought and Image of some fearfull object
(the motion from the brain to the inner parts, and from the
inner parts to the Brain being reciprocall:) and that as Anger
causeth heat in some parts of the Body, when we are awake;
so when we sleep, the over heating of the same parts causeth Anger,
and raiseth up in the brain the Imagination of an Enemy.
In the same manner; as naturall kindness, when we are awake
causeth desire; and desire makes heat in certain other parts
of the body; so also, too much heat in those parts, while wee sleep,
raiseth in the brain an imagination of some kindness shewn.
In summe, our Dreams are the reverse of our waking Imaginations;
The motion when we are awake, beginning at one end; and when we Dream,
at another.

The most difficult discerning of a mans Dream, from his waking thoughts,
is then, when by some accident we observe not that we have slept:
which is easie to happen to a man full of fearfull thoughts;
