My birthmark is on my..... um...... super lower back I guess....... I’m scared and weirded out at myself at the same time

I follow where “your birthmark area is where you died” and I remember my mom says when I was little I would talk about how I was in a house with wood walls, and dirt floors (I’m guessing I was a peasant in medieval times idk) and I said “when I woke up, everyone was dead and then I died.” (I’m guessing from a plague from back then. Well shit lmao
