Consciousness or the waking state is the condition in which active communication
with the external world exists through the intermediation of the senses. It
may undergo various modifications, some of a normal character, as in sleep,
others of a morbid character, such as coma. During sleep, there is reason
to believe, certain subconscious processes, partly of perception, partly of
ideation, continue, and of which there is at times recollection and at other
times none. This statement is exemplified in connection with dreams. In the
derangements of consciousness symptomatic of morbid states, such as that which
occurs, for example, in the course of epilepsy or of uremia, there is, as
a rule, no memory of events that have transpired during this time. The dividing
line between the normal and the abnormal, however, is at times so tenuous
and the question of recollection or not is involved in so much uncertainty
that this factor can not be considered as a means of differentiation.
