Final answer:
Jeanette's feeling of recognizing a man she has never met is likely due to the phenomenon of 'déjà vu,' a common memory anomaly where a new situation feels familiar without an actual previous encounter.
Step-by-step explanation:
Jeanette's feeling of familiarity towards the man she has never met before is most likely a result of a phenomenon known as 'déjà vu', which is a French term meaning 'already seen.' This sensation occurs when a person feels an unwarranted sense of recognition in a situation that is objectively new or unfamiliar. Déjà vu is a common experience that has been described in various cultural contexts and is sometimes associated with a sense of prophecy, but it is generally regarded by psychologists as a type of memory anomaly. It may happen if a particular pattern or scene aligns with a fragment of a memory that does not have a clear context, causing someone to feel as if they've been in that exact moment before despite it being a new encounter.
