" These subliminal aspects of everything that happens to us may seem to play very little part in our daily lives. But in dream analysis, where the psychologist is dealing with expressions of the unconscious, they are very relevant, for they are the almost invisible roots of our conscious thoughts. That is why commonplace objects or ideas can assume such powerful psychic significance in a dream that we may awake seriously disturbed, in spite of having dreamed of nothing worse than a locked room or a missed train.
