Much of this phantasy thinking was seen to be scarcely conscious, but arose from unrealized wishes, desires and strivings which could only express themselves through veiled symbols in the form of phantastic structures not understood, nor fully recognized. Indeed, it is perhaps one of the most common human experiences to find “queer thoughts,” undesired ideas and images, forcing themselves upon one’s attention to such an extent that the will has to be employed to push them out of mind. It is not unusual to discover long-forgotten impressions of childhood assuming a phantastic shape in memory, and dwelt upon as though they were still of importance. This material afforded a rich field for the searchers into the soul, for through the operation of the law of association of ideas these phantastic products, traced back to their origin, revealed the fact that instead of being meaningless or foolish, they were produced by a definite process, and arose from distinct wishes and desires which unconsciously veiled themselves in these mysterious forms and pictures. It is conceded that the most completely unconscious product of an individual is his dream, and therefore Professor Freud turned his attention from phantasies and day-dreams to the investigation of the nightly dreams of his patients to discover whether they would throw light upon the painful feelings and ideas repressed out of consciousness, and therefore inaccessible to direct revelation. This brilliant idea soon led to a rich fruiting, for it became evident that contrary to the usual conception that the dream is a phantastic and absurd jumble of heterogeneous fragments, having no real relation to the life of the individual, it is full of meaning. In fact, it is usually concerned with the problem of life most pressing at the time, which expresses itself not directly, but in symbolic form so as to be unrecognized. In this way the individual gains an expression and fulfilment of his unrealized wish or desire.
