[Footnote 147: In the other spheres in which symbolism most tends to appear, the same or allied conditions exist. In hallucinations, which (as Parish and others have shown) tend to occur in hypnagogic or sleep-like states, the conditions are clearly the same. The symbolism of an art, and notably music, is due to the very conditions of the art, which exclude any appeal to other senses. The primitive mind reaches symbolism through a similar condition of things, coming as the result of ignorance and undeveloped powers of apperception. In insanity these powers are morbidly disturbed or destroyed, with the same result.] [Footnote 148: The magnification we experience in dreams is manifested in their emotional aspects and in the emotional transformation of actual sensory stimuli, from without or from within the organism. The size of objects recalled by dreaming memory usually remains unchanged, and if changed it seems to be more usually diminished. 'Lilliputian hallucinations,' as they are termed by Leroy, who has studied them (_Revue de Psychiatrie_, 1909, No. 8), in which diminutive, and frequently coloured, people are observed, may also occasionally occur in alcoholic and chloral intoxication, in circular insanity, and in various other morbid mental conditions. They are usually agreeable in character.] [Footnote 149: Sollier, 'L'Autoscopie Interne,' _Revue Philosophique_, January 1903. Sollier deals with the objections made to the reality of the phenomenon.] [Footnote 150: 'Many people,' writes Dr. Marie de Manacéïne (_Sleep_, 1897, p. 294), 'when threatened by a gastric or intestinal attack dream of seeing fish. The late Professor Sergius Botkine told me that he had found this coincidence in his own case, and I have myself several times found it in the case of a young girl who is well known to me. Some have supposed that the sleeping consciousness receives an impression of the elongated shape of the stomach or intestine; but such a supposition is easier to make than to prove.' Scherner associated dreams of fish with sensations arising from the bladder, and here also it may be said that we are concerned with a fish-like viscus. Greenwood (_Imagination in Dreams_, p. 195) stated that he had always been subject, at intervals of months or years, to a recurrent dream in which he would see a river swarming with fish that were finally piled in a horrible sweltering mass; this dream always left a feeling of 'squalid horror,' but he was never able to ascertain its cause and significance.] [Footnote 151: Freud states (_Die Traumdeutung_, p. 233) that he knows a case in which (as in the _Song of Songs_) columns and pillars appear in dreams as symbols of the legs, and doors as symbols of the openings of the body.]
