In the process of consolidating an episodic memory, your brain is like a sticky-fingered, madcap chef. While it stirs together the ingredients of what you noticed for any particular memory, the recipe can change, often dramatically, with additions and subtractions supplied by imagination, opinion, or assumptions. The recipe can also be warped by a dream, something you read or heard, a movie, a photograph, an association, your emotional state, someone else’s memory, or even mere suggestion.
