I've heard of, and experienced, 'false memory' though.
I have a photo of my daughter as a toddler sporting a rather cute pudding-basin hair cut. She swears she distinctly remembers me cutting her hair by actually using a pudding basin on her head and cutting around it.
I did no such thing, her hair was cut at the hairdressers'.
If you can be bothered to try it yourself you'll see its well nigh impossible.
She's convinced however and delights in telling all and sundry its a fact!
(Sorry, that doesn't help the discussion one little bit, does it
)
