I'd never thought this was weird, but I've been debating it ever since Marlowe pointed it out to me. But I still believe that there must be people out there who used to do the same thing: as a kid, instead of wanting to play house or princess, I wanted to pretend I was freezing in the tundra or wandering lost and hopeless in the woods with my stuffed animals (children) and desperate for food.
I'm still convinced this is perfectly normal.
