The method of producing crystal visions may also be used to demonstrate the dormant conservation of experiences originating in hypnotic states. By this method and that of automatic writing, as I have already explained, the memories may be made to reveal themselves, without inducing recollection, at the very moment when the subject cannot voluntarily recall them. The subject, of course, being ignorant of what happened in hypnosis cannot recognize the visions as pictorial memories. In illustration of this I would recall the observation in the case of Miss B. where, in such an artificial vision, she saw herself sitting on a sofa smoking a cigarette.[34] This vision represented an incident which occurred during one of the subject’s hypnotic states when she had smoked a cigarette. Naturally Miss B., in her ignorance of the facts, denied the truthfulness of the vision. Other examples of a like kind might be cited if it were necessary. By automatic writing, also, evidence of the same principle may be obtained. The conserved memories are _tapped_, so to speak. Thus I suggest to Mrs. R. in hypnosis that after waking she shall write certain verses or sentences. After being awakened she reproduces automatically, as directed, the desired verses or sentences which, of course, belonged to her hypnotic experiences.[35] In other words, although the personal consciousness did not remember the hypnotic experience of having received the command and of having given the promise to write the verses, etc., the automatic writing by the act of fulfilling the command showed that all this was conserved; here again was evidence of conservation, in some form, of an experience at the very moment when the personal consciousness was unable to voluntarily recall what had taken place in hypnosis. Such experiments may be varied indefinitely.
