In Gneki's view, the operation and makeup of dreams completely distort the manifestation of dreams through the process of compression, feature displacement and secondary correction. Compression refers to the transformation of dreams with manifestations into simple forms, in which some components of dreams are omitted and others only appear in incomplete forms. Displacement means that an unimportant idea becomes a trivial matter, while a dream becomes a major event or occupies an important position. Symbolism means replacing abstract desires with concrete forms. It shows that dreams are the real path to the subconscious; The contents that can be formed (changes, contradictions, reasons) reflect the logical relationship, but appear in a brand-new way. The second correction is to systematize the disordered materials in the dream to cover up the truth.
