The complete abandonment to the interesting image explains also the wonderful naturalness of pseudological or somnambulic representation--a degree unattainable in conscious acting. The less waking consciousness intervenes by reflection and reasoning, the more certain and convincing becomes the objectivation of the dream, e.g. the roof-climbing of somnambulists.
Our case has another analogy with _pseudologia phantastica_: _The development of the phantasies during the attacks._ Many cases are known in the literature where the pathological lying comes on in attacks and during serious hysterical trouble.[79]
Our patient develops her systems exclusively in the attack. In her normal state she is quite incapable of giving any new ideas or explanations; she must either transpose herself into somnambulism or await its spontaneous appearance. This exhausts the affinity to _pseudologia phantastica_ and to pathological dream-states.
Our patient's state is even differentiated from pathological dreaming, since it could never be proved that her dream-weavings had at any time previously been the objects of her interest during the day. Her dreams occur explosively, break forth with bewildering completeness from the darkness of the unconscious. Exactly the same was the case in Flournoy's Helen Smith. In many cases (see below), however, links with the perceptions of the normal states can be demonstrated: it seems therefore probable that the roots of every dream were originally images with an emotional accentuation, which, however, only occupied waking consciousness for a short time.[80] We must allow that in the origin of such dreams hysterical forgetfulness[81] plays a _part not to be underestimated_.
Many images are buried which would be sufficient to put the consciousness on guard; associated classes of ideas are lost and go on spinning their web in the unconscious, thanks to the psychic dissociation; this is a process which we meet again in the genesis of our dreams.
"Our conscious reflection teaches us that when exercising attention we pursue a definite course. But if that course leads us to an idea which does not meet with our approval, we discontinue and cease to apply our attention. Now, apparently, the chain of thought thus started and abandoned, may go on without regaining attention unless it reaches a spot of especially marked intensity, which compels renewed attention. An initial rejection, perhaps consciously brought about by the judgment on the ground of incorrectness or unfitness for the actual purpose of the mental act, may therefore account for the fact that a mental process continues unnoticed by consciousness until the onset of sleep."[82]
