“... the kind of subliminal material from which the symbols of our dreams may be spontaneously produced. This subliminal material can consist of all urges, and intentions; all perceptions and intuitions; all rational or irrational thoughts, conclusions, inductions, deductions, and premises; and all varieties of feeling. Any or all of these can take the form of partial, temporary, aur constant unconsciousness.” Dreams Book:Man and His Symbols Source: Man and His Symbols
