Includes Extramission 2 (The Trilogy) by Lindsay Seers. A false memory is the recollection of something that did not happen or happened differently from the actual events, without consciously intending to deceive or mislead. False memories are often incredibly realistic, and it can be difficult to differentiate between what really happened and what is being remembered. This makes it hard to convince the person recalling the false memory that the event they so clearly remember, in fact, happened differently, or not at all.
