My understanding of this is illuminated by (stay with me here...) blockchains. Most blockchains use a kind of time-traveling/holographic data structure where a given tree root can be used to lookup state values in a big trie, for some block in the past. Different root, potentially different value for the state you're interested in. The brain seems to be operating a similar data structure where the answer to your query depends on some sort of "neural net root" value. This value seems to come from primitive structures (HPA?) and depends on basic things like fight/flight anxious/relaxed. The upshot is that people can believe/think/know different things depending on their current emotional state.
