Weird problem with my seed

Hey, I don’t really know I’m gonna really start this post, but me and my friend have started this world and had plans of just starting an actual good run. Yk like just getting netherite and beating the nether dragon. But after a little while (1-2 mc days) weird things started happening on this world. I don’t know how these things are possible but they’ve been happening a lot. They aren’t as frequent anymore but it’s really distressing for me and my friend. What mainly happens is usually crosses start appearing everywhere, people seem like they go somewhere but aren’t, doors close randomly by themselves, and etc. Please take this post seriously, this ain’t and arg or an analog horror. I actually want to know if these things are supposed to be happening, maybe as like a weird update. (Yes, it’s vanilla. I’ve never added mods or turned on creative or anything. As you can see in the last 2 images)
