I think you mean like when i reflect on the day alone in a relaxing environment and the events of the last few days flow through my mind and i put together patterns i did not see before? it is a sensation i don't quite get and all the sudden i may find things that astound me that i could not see. i sometimes figure out what a person is hiding from me or something i may have been oblivious to will be plain as day.
Nfs suffer from that a lot, I believe.
When I was younger and less mature I would be able to get a pretty good read on people (See their hidden agendas, etc)...
However, the moment that my emotions such as sympathy, love, anger, or anything else came into play, it was like I would completely bury my head in the sand and I'd read people 110% wrong. It was like my judgement of people, which are usually reliable and scary accurate, get totally thrown off by my emotions.
I would have a hard time seeing any wrong or negative traits in women where love was involved... I'd have a very hard time seeing bad or negative traits in people I saw as "victims". And on the flipside... I had a very hard time seeing the good parts of people that I considered to be evil.
My emotions replaced my desire to see the truth, and replaced it with a desire to see a "particular" truth that I hoped for. Unfortunately the world wasn't as black and white as I wanted to paint it as a kid, and I had to learn from it.
