For years I lived in close relation with neurotic, psychopathic patients. I watched them day and night. I have been called by patients for medical aid in the late hours of the night, and more so during the vigil hours of the darkness of the night. I had to relieve and soothe the fears, the terrors of the night. It is in the night, when in a low state of neuron energy that patients feel the grip of horrors oppressing them with nightmares of the relentless and merciless instinct, the fear instinct. To be relieved of the night terrors many patients are willing to risk anything, even the consequence of deadly narcotics, the plagues of mental healers, and the sexual phantasms of Psychoanalysis. The hypnoidal state is induced artificially, often brought about by intoxication, as in the case of holy Soma drink among the Hindoos, or by fasting, as among the American Indians during the initiation periods, or by dancing, such as the corrobboree among the aborigines of Australia, or by singing, or by praying. All the conditions of disjunction of consciousness with the manifestations of subconscious activities are brought into play, in order to come in contact with demons, spirits, totems, and find among them guides and protectors. In prolonged hypnoidal states, the fear instinct and the impulse of self-preservation are calmed under appropriate conditions. Illusions and hallucinations which easily appeared in the twilight states of hypnoidal subconscious states became manifested as beneficent spirits, as agents favorable to the life existence of the individual, the spirit appearing as the totem, the guardian of the individual. Prayer and singing, which are the most successful of all the methods of inducing subconscious subwaking, twilight states, have survived to our present day. Of all the methods of utilization of subconscious subwaking, twilight states the most effective is prayer, especially, the individual form of prayer. Prayer admirably fulfills the conditions requisite for the induction of the hypnoidal state and for the getting access to the subconscious activities, the formation of subconscious personalities, subconscious illusions and hallucinations. Such subconscious states have been shown, on experimental evidence, to be not of a sensory, but of a purely delusional character, strong enough to affect the individual with an intense belief in its external reality. The deluded human mind in its craven fear of the unseen and the mysterious spirit-forces helps itself to any soporific or anaesthetic, narcotic stimulant, to bring about a scission of the conscious self from the subconscious activities. The induction of the hypnoidal state is brought about by all kinds of intoxicants, narcotics, fasting, dancing, self-mortification, sex excesses which exhaust the devotee, and leave him in a state of trance. All such practices and rites seek blindly for some trance-state to still the morbid fear instinct.
