Impossible to convince those that sleep without dreaming, that they think.       §13. Thus, methinks, every drowsy Nod shakes their Doctrine,
who teach, That the Soul is always thinking. Those, at least, who
do at any time sleep without dreaming, can never be convinced, That
their Thoughts are sometimes for four hours busy without their
knowing of it; and if they are taken in the very act, waked in the
middle of that sleeping contemplation, can give no manner of
account of it.
Locke Hum II, 1, §13, p. 111
