ABSTRACT
All forgetting and remembering has two aspects in general: Both these aspects of remembering and forgetting apply to dreams. The removal of attention cathexis from current thoughts and perceptions so that other thoughts and perceptions can enter consciousness in their turn. The original thoughts and perceptions leave memory traces from which, by later processes of condensation and displacement of cathexes are constructed images and concepts. The memory-traces themselves persist unchanged and not organized. There is the other aspect, relating to the pleasure principle of the inability to recall certain memories to consciousness at will, because their content would in itself cause anxiety or unpleasure or because they are unconsciously associated with other memories which are barred from consciousness for the same reasons.
