There is a lot of evidence that suggests memories are actually very sketchy, with few details really remembered.
When e.g. a scene once seen is recalled, all the missing details are filled in by the mind before we become aware of the memory, so it presents itself to the conscious mind as a complete scene with nothing to show what's made up and what's actually remembered.
But the majority of what's remembered is actually put in afterwards.
This can be shown by e.g. taking a very well-known iconic image such as the guy standing in front of a column of tanks on the way to Tienanmen square, digitally line the street with spectators and then showing the new version to people and asking what's wrong with it. Almost nobody remembers the sides of the street because they were not where the action happened, so seeing the spectators will retroactively correct the memory to add them.
And for that matter, asking later how many people were seen on the images will have people now recall the spectators because the memory has been altered by being refreshed by the new version.
This is true for every normal human being, it's just how memory works. It's quite normal to have people recall events in great detail and be able to describe everything, even the tiniest of minutae, but the vast majority is actually not recalled but is something filled in by the memory system from scratch.
This is one of the important reasons why eye-witness testimony is the weakest form of evidence, even when the witness it trying very hard to say exactly what they remember, a lot of what's remembered will not actually be real memory.
Reductionist and proud of it.
