I have brought it up with a few friends and most have heard the same!

Well, that is not a indication that it is not a false memory, as the thing you describe is core part of how these kind of collective false memories are probably formed, by "social and cognitive reinforcement":

Scientists suggest that these are examples of false memories shaped by similar cognitive factors' affecting multiple people and families, such as social and cognitive reinforcement of incorrect memories

I have been e.g. affected by the (known) Mandela Effect false memory of the Fruit-of-the-Loom logo having had a cornucopia.
I have seen the clear evidence that it has not, but I still have the memory, which feels absolutely real.
It is a really strange feeling... No wonder it sparked the idea by some that these kind of false memories are spill-overs from alternate timelines or parallel universes :-)
