Does anyone else do imagination-y stuff like this?

Well I think I've got you all beat with the story of the whos and the lice.

Basically when I was 7 I didn't play with the other kids much, so I started creating this imaginary world in my head. We'd read Horton Hears a Who in class, and we'd been inspected by the school nurse for headlice just a few weeks before, so I created the "whos" and the "lice," who were at war in an epic tale of good v.s. evil. I used twigs and paperclips as giant battlecruisers floating in the air (it wasn't space, they were like Star Wars ships, just in the atmosphere), and bits of eraser as tanks. I had characters, too, though only a few at the start. I continued this through elementary and middle school, each school being a massive Death-Star-like superfortress the lice had, that was eventually "blown up" when I left the school.

Then I was homeschooled for a year, and I started to do this in my head at home when I was bored outside. Not with twigs and paperclips or anything physical, just in my head. The whos had fled to Sarengarth, a tree outside my house, that was a massive who city, a nearly impenetrable fortress. Basically ever since, for more than 13 years, whenever I am bored, this story goes inside my head. There has been mystery, conquest, success, failure, villains, birth and death over three generations of the family of the main characters.

It's weirder than probably most anything, but it stays in my head and it won't go away. I think the story of the whos and lice might continue for the rest of my life.
