I fell asleep on my hand, it appears - so it's left a mark on my belly. It looks really weird, actually. And it's happened before too, but then it was on my leg. I have no idea why I still halfway to Legoland awoke and took this picture. But I found just the whole concept of dragging myself out of bed to document this absurdness so bizarre that I decided to share the bizarreness with you.
