The term "random memory" can refer to any memory that is not intentional or significant. Some synonyms for this term include spontaneous memory, incidental memory, chance memory, and unintentional memory. Spontaneous memory refers to a memory that arises naturally, without conscious effort. Incidental memory refers to a memory that is acquired coincidentally, without intention. Chance memory refers to a memory that is picked up by accident, in a manner that is unpredictable. Finally, unintentional memory refers to a memory that is not deliberately encoded or retrieved, but rather emerges spontaneously. All of these synonyms share the idea that the memory in question is not deliberately chosen or particularly meaningful.
