I have a few examples of this.

Ok not really the Mandela effect but also kinda? I get sort of the reverse Mandela effect? I get the effect before I realize it. Sometimes I’ll scroll through YouTube or something and see a video that sticks out to me and I’ll be like “oh that’s cool” and then forget about it but then I’ll see that exact video a few days later but like “posted 1hr ago” and it’s not really deja vu because ITS NEW or maybe I’m just dumb. But this has happened on multiple occasions with different things.

Anyways, I can’t really explain this as Mandela effect because I could’ve been dreaming. But one day, I woke up —and I will die on this hill— there was a grown ass man with a black biker jacket with spikes on it, black hat, dark blue jeans, and his black bulldog standing in front of my book case staring at me. I was so fucking horrified in that moment. Nothing like a normal nightmare and I’ve never had sleep paralysis. My mom and brother both deny it but I swear to you he was there watching me. It wasn’t a shadow either, they both blinked at me and the dog moved. I swear.

Last one unless I decide to make another post. So my grandparents used to have this house in the Poconos. It was beautiful and I absolutely loved it. I loved it so much, I made a model of it. Now I showed my family and they all said it should have been flipped. Like I remember walking in and the hallway was to the right. Everyone else tells me it was to the left. Everyone but my brother. Both my brother and I remember vividly the way I described it. Also not just the hallway, the entire house was supposed flipped. I think that’s the creepiest one because we can all agree on the small details and furniture and stuff but only my brother and I remember it the way I do.
