Does anyone else have a strong urge to worldbuild a single, extremely specific event in history?

I'm not sure if I'm just really really weird, or if I'm not the only one who does this. I've been doing it basically forever, and I can't even begin to count how many worlds I've built based on tiny events that I'm not even sure actually happened. Usually I'm inspired by one small detail, or something that's mentioned once and then completely forgotten. I guess I like building worlds around them because I can more or less do whatever I want, but also there are certain specifics that must be followed. <br><br>I'm not talking about alternate history, or anything like that. Everything's hypothetically happening exactly as it was in our timeline. It's just that I build everything that happened around that event. For an example: I once read in a book about the Byzantine empire that the last empress was seen in a doorway on the second floor of the palace with a child, and then was never seen again. I've built a world, and a life, around her. <br><br>I just can't help it. Every time I read a history book, I find myself completely absorbed in the details within it, and I can't stop thinking about them. I get images of what it looked like, would have looked like, or could have looked like. I imagine sounds, and smells. Sometimes I'll even hear what it would have sounded like. I know it's technically hallucinations, but I can't help it. It feels kind of like I'm there. I get obsessed with every tiny detail. Every person, big or small. <br><br>Worldbuilding like that might just be a weird coping mechanism, or it might be something else. Either way, I don't want to stop. I just want to know if I'm the only one.<br><br>Edit: wow, this blew up. Thank you all so much.
