@FreeDuck,
Memory is freaky.
I have a few different "brains are weird" books and I don't remember which one I'm thinking of, but it was really amazing how in various experiments, people had false memories implanted EASILY.
Oh, I may be thinking too of a series on PBS, Alan Alda was the host, I remember something about photographs of an experience vs. the actual experience...
Anyway, memory is freaky. It's way more malleable and changeable than most people think. (Which is itself a freaky idea.)
Another tidbit I remember -- people remember the last time they told a story more than the original experience itself. So if they change a detail in the telling of the story, that detail becomes their memory of the experience. (Unless the detail is big enough that a "oh right I was lying about that" flag goes up.)
