Here's one I just experienced, was watching Star Wars: A New Hope and my brother asked me if I remember C-3PO every having a silver leg. I told him no, hes always been all gold. Next scene we watched his right leg from the knee down was all silver. Like wtf never have I noticed that before, I said meh maybe it was a Lucas later edit. Revenge of the Sith comes on the TV next and C-3PO's leg is so vibrantly silver that I could not even comprehend not noticing that contrast in past viewings.

When i got into monster hunter 4 ultimate(the one with a good story) i was told that Deviljho, a voracious monster that will eat anything mid combat to recover its stamina, will eat its own tail if you cut it. Everyone believed it, no one tried to capture it on camera because of the hardware limitation(no "clip that", no shadowplay).

Turn out, millions of Monster Hunter fans remembered wrong because it's a hoax.

I could’ve sworn Jim Beam whiskey was Jim Bean. A friend of mine had a poster of a whiskey bottle on his wall that I stared at every time I was there. He was a minor at the time and didn’t drink, so I always wondered why he had it up. Years later I saw a Jim Beam bottle and had a Mandela moment. The Berenstein Bears and Mandela dying in jail were things I believed, too, but I think the whiskey one is one I haven’t heard from anybody else, yet.
