It is not only in sleep that the sensation of flying is experienced. In hysteria a sense of peculiar lightness of the body, and the idea of the soul's power to fly, may occur incidentally,[126] and may certainly be connected both with the vigilambulism, as Sollier terms the sleep-like tendencies of such cases, and the anaesthetic conditions found in the hysterical. It is noteworthy that Janet found that in an ecstatic person who experienced the sensation of rising in the air there was anaesthesia of the soles of the feet. In such hysterical ecstasy, which has always played so large a part in religious manifestations, it is well known that the sense of rising and floating in the air has often prominently appeared. St. Theresa occasionally felt herself lifted above the ground, and was fearful that this sign of divine favour would attract attention (though we are not told that that was the case), while St. Joseph of Cupertino, Christina the Wonderful, St. Ida of Louvain, with many another saint enshrined in the _Acta Sanctorum_, were permitted to experience this sensation; and since its reality is as convincing in the ecstatic state as it is in dreams, the saints have often been able to declare, in perfect good faith, that their levitation was real.[127] In all great religious movements among primitive peoples, similar phenomena occur, together with other nervous and hallucinatory manifestations. They occurred, for instance, in the great Russian religious movement which took place among the peasants in the province of Kief during the winter of 1891-2. The leader of the movement, a devout member of the Stundist sect, a man with alcoholic heredity, who had received the revelation that he was saviour of the world, used not only to perceive perfumes so exquisite that they could only, as he was convinced, emanate from the Holy Ghost, but during prayer, together with a feeling of joy, he also had a sensation of bodily lightness and of floating in the air. His followers in many cases had the same experiences, and they delighted in jumping up into the air and shouting. In these cases the reality of the sensory obtuseness of the skin as an element in the manifestations was demonstrated, for Ssikorski, who had an opportunity of investigating these people, found that many of them, when in the ecstatic condition, were completely insensible to pain.
