The one that gets me is Australia. I saw someone talking about New Zealand being at '4 o'clock' to Australia, and I thought to myself 'haha! It's at 2 o clock'.
Thought nothing of it, until I heard about it as part of the Mandela effect - I immediately ran to my globe, and OMG! New Zealand is at 4 o'clock! And there's loads of islands almost touching Australia!
Now I know that New Zealand was at 2 o'clock, and Australia was in the middle of nowhere - nothing anywhere near it, certainly not almost touching it.
So I phoned my sister and asked her to look at my brother's old globe and tell me where New Zealand was (I wouldn't explain further). She came back going 'OMG, it's in the wrong place and so is Australia!' We have that same memory of their positions.
Next time I saw ex-DH, I asked him 'if Australia is a clock, where is NZ?' He thought 2 o' clock too, and was just as amazed when I showed him.
My impression is that older people remember Australia out on its own, with NV at 2 o' clock, and younger people remember it the way it is now - but not 100 per cent either way.
We spent a term doing Australia as a project in Geography at school. I don't care if it makes me a narcissist to trust a memory I had no reason to doubt until recently, and having so many of my peers share the memory must mean there's a lot of us Ns about!
Or maybe 70s maps are wrong? But that doesn't explain the change to my brother's globe.
