And yet the vision pictured everything exactly as it had occurred in my presence, even to the expression of her features. Looking into the crystal the subject saw herself sitting in a particular place, enacting a series of movements, talking and smoking a cigarette with a peculiar smile and expression of enjoyment on her face.[91] For this experience there was complete amnesia after waking from hypnosis and at the time of the vision. Now consider further the facts and their implications. In the mechanism of the process eventuating in the visual phenomenon we obviously have two known factors: the antecedent causal factor—the hypnotic episode—and, after a time interval, the end result—the vision. As there was no conscious memory of the hypnotic episode the neurograms of the latter must have functioned subconsciously to have produced the vision. But what particular neurograms? As the subject’s eyes had been closed in hypnosis, and, in any event, as she could not have seen her own face, there were at the time no _visual_ perceptions of herself smoking a cigarette, and therefore the vision could not have been simply a reproduction of a visual experience. There were, however, tactual, gustatory, and other perceptions and ideas of self and environment, and these perceptions and ideas of course possessed _secondary visual images_.[92] The simplest mechanism would be that the neurograms of this complex of perception and ideas of self, etc., functioned subconsciously and their _secondary_ visual images emerged into consciousness to be the vision. I give this as the simplest mechanism by which we can conceive of a visual representation of an antecedent experience emerging out of a subconscious process.[93] There is a considerable body of data supporting this interpretation.
