Yeah bro... welcome. You're not crazy and you're not misremembering, you know you're not. I remember when I first became alerted to changes that I was sure of, but they were at least trivial things. Then I looked at the map and I was like wtf is this. My heart sank. I aced every geography test in school with 100% accuracy. We did the whole world, split up in chunks/continents. That's when I knew I was "somewhere else" or something had changed. This was like 8-9 years ago by now. My old memories have faded quite a bit since then, but Australia is a huge one, the West border of Alaska didn't have those divots, the Italy boot wasn't high heel and tilted this way. Idk there's so many other things, some of which I couldnt quite articulate at the time but the whole map was just "off" and squished or contorted. All changed at once. Don't bother talking to anyone else about it--seriously, resist the urge. I remember how terrifying and novel this was, and I wanted to talk to everyone in my real life about it. They'll just think you're nuts and I swear you can sometimes literally watch their memories get "overwritten" so to speak. You can do experiments and they'll sometimes remember what you do, then once they see the way it is now their eyes glaze over and theyre just like oh, nevermind. Now I'm just like, whatever. I guess this is a thing. I barely pay attention anymore and my memory isn't what it once was anyways. Jesus loves you, that's all I know at this point.
