StephenT, woman is a very complex being!
Joking aside, we do have a different emotional make up to men. Realise that's a simplistic explanation but it seems the most straight-forward. An example, when asked what colour his partner's dress is, he'll say blue. To him, that's how he sees it. Ask his partner and her answer will be it's royal blue, because she has a wider descriptive ability.
A woman will naturally elaborate on what she's saying by telling a relevant story to support. How far she goes with credibility is either her enhancement of the topic based on true personal experience, or exaggeration/lying for whatever reason. Stuff can be made up by anyone with good or bad intentions.
It could be she wants to provide a detailed scenario to enhance what she's saying. Or worst case, she is lying. Unfortunately, because we are all different and far more complicated than Mars/Venus, it can take time before we "call them out".
