I also have a story to share:
About 15 years ago two professors and an assistant professor (me) were sitting in a restaurant at Constance University and talking about many things. Then the older of the two professors talked about his doctoral dissertation way back in 1954 and how the oral examination had to be postponed because professor B. who was scheduled to examine him had shot himself in his office. He told with vivid detail about his own emotions as the secretary came out to tell him and how he was shattered and that he had to choose another examiner.
Then the other professor said. "You must have mixed up the date, for B. shot himself in 1955." "No, no, I'm completely sure. You see, that's not a minor detail of my life. I just know when I made the examination and that it had to be postponed because of the suicide". They made a wager with me being the uninterested third party. I volunteered to go into the library and came back with a xerox of the obituary. It said 1955. The older professor was visibly shattered and refused to believe the obituary ('they make mistakes in obituaries, you know'). A part of his recollection of his own life was demonstratably wrong and it was not a minor part. It was so filled with emotions that he just couldn't believe he was wrong. He refused to pay for the wager on the spot. He payed months later without any comment at that time. He told much later he had checked several other obituaries (B. was famous enough to have several) and had checked the old records of his university to find that he made his dissertation in 1954 about one year before the death of B. Nevertheless, his recollection of what he had told us was still as vivid as ever though he accepted now it was wrong.
The cases in which the recollection of a story can be checked against reality (like in the above case) are obviously very rare. When it has been done (scientists have tried that with ghost or similar stories since at least 1884) it often has been found that memories were not only in minor details wrong. Wrong memories can easily be induced in laboratories and in real life experiments. Since I do among other things research about illusions of memory I could tell you easily of more experiments or investigations showing wrong memories than you can tell me stories. For a bit more of my opinion you could read the last bit of my post in the crop circles thread.
From my point of view, you should have a bit less confidence in your recollections than you seem to have.
