Final answer:
Freud asserts that the elements of our dreams are often overdetermined, shaped by unknown psychical forces diminishing high-value elements while elevating low-value elements into dream contents.
Step-by-step explanation:
Freud's concept of overdetermination suggests that the elements of a dream are conditioned by multiple factors and reinforced from various directions in the psyche. The multiple determination of dream content raises the idea that these factors are not always primary in the construction of dreams, but might be the result of secondary psychical forces that are not completely understood. Freud identifies a psychical force that seemingly diminishes the intensity of elements with high psychological value while enhancing elements of low psychological value, thereby allowing them to enter the dream-content through overdetermination.
This force could refer to underlying defense mechanisms or the unconscious mind's effort to resolve inner conflicts. When Freud discusses this psychical force 'creating new values,' he implies that elements with low inherent psychological importance can become significant in the dream due to being overdetermined. This condition allows these elements to be included in the dream's content. The reference to the botanical monograph suggests that a seemingly trivial detail can achieve prominence in a dream narrative through this process.
