At all times the complex hallucinations of visionaries have occupied a peculiar place in scientific criticism. Macario[54] early separated these so-called intuition-hallucinations from others, since he maintains that they occur in persons of an eager mind, deep understanding and high nervous excitability. Hecker[55] expresses himself similarly but more enthusiastically. His view is that their condition is "the congenital high development of the spiritual organ which calls into active, free and mobile play the life of the imagination, bringing it spontaneous activity." These hallucinations are "precursors or signs of mighty spiritual power." The vision is "an increased excitation which is harmoniously adapted to the most complete health of mind and body." The complex hallucinations do not belong to the waking state, but prefer as a rule a partial waking state. The visionary is buried in his vision even to complete annihilation. Flournoy was also always able to prove in the visions of H.S. "un certain degré d'obnubilation." In our case the vision is complicated by a state of sleep whose peculiarities we shall review later. THE CHANGE IN CHARACTER. The most striking characteristic of the second stage in our case is the change in character. We meet many cases in the literature which have offered the symptom of spontaneous character-change. The first case in a scientific publication is Weir-Mitchell's[56] case of Mary Reynolds. This was the case of a young woman living in Pennsylvania in 1811. After a deep sleep of about twenty hours she had totally forgotten her entire past and everything she had learnt; even the words she spoke had lost their meaning. She no longer knew her relatives. Slowly she re-learnt to read and write, but her writing was from right to left. More striking still was the change in her character. Instead of being melancholy, she was now cheerful in the extreme. Instead of being reserved, she was buoyant and sociable. Formerly taciturn and retiring, she was now merry and jocose. Her disposition was totally changed.[57] In this state she renounced her former retired life and liked to undertake adventurous excursions unarmed, through wood and mountain, on foot and horseback. In one of these excursions she encountered a large black bear, which she took for a pig. The bear raised himself on his hind legs and gnashed his teeth at her. As she could not drive her horse on any further, she took an ordinary stick and hit the bear until it took to flight. Five weeks later, after a deep sleep, she returned to her earlier state with amnesia for the interval. These states alternated for about sixteen years. _But her last twenty-five years Mary Reynolds passed exclusively in her second state._
