These selected cases of various forms of changes of consciousness all throw a certain light upon our case. Naef's case presents two hysteriform eclipses of memory, one of which is marked by the appearance of delusions, and the other by its long duration, contraction of the field of consciousness, and desire to wander. The peculiar associated impulses are specially clear in the cases of Proust and Mesnet. In our case the impulsive tearing up of the flowers, the digging up of the graves, form a parallel.

The continuity of consciousness which the patient presents in the individual attacks recalls the behaviour of the consciousness in MacNish's case; hence our case may be regarded as a transient phenomenon of alternating consciousness. The dreamlike hallucinatory content of the limited consciousness in our case does not, however, justify an unqualified assignment to this group of double consciousness.

The hallucinations in the second state show a certain creativeness which seems to be conditioned by the auto-suggestibility of this state. In Mesnet's case we noticed the appearance of hallucinatory processes from simple stimulation of touch. The patient's subconsciousness employs simple perceptions for the automatic construction of complicated scenes which then take possession of the limited consciousness. A somewhat similar view must be taken about our patient's hallucinations; at least, the external conditions which gave rise to the appearance of the hallucinations seem to strengthen our supposition.

Wowie
The walk in the cemetery induces the vision of the skeletons; the meeting with the three boys arouses the hallucination of children buried alive whose voices the patient hears at night-time.[12] She arrived at the cemetery in a somnambulic state, which on this occasion was specially intense in consequence of her having taken alcohol. She performed actions almost instinctively about which her subconsciousness nevertheless did receive certain impressions.

These lapses of memory, which at first seem without content, gain a content by means of accidental auto-suggestion, and this content builds itself up automatically to a certain extent. It achieves no further development, probably on account of the improvement now beginning, and finally it disappears altogether as recovery sets in. Binet and Féré have made numerous experiments on the implanting of suggestions in states of partial sleep.
