One weird thing is to fall asleep in a coffee shop. That happened to me this evening. Even if I wasn't drinking straight coffee, I was caffeinated enough. Well, except I hadn't gotten nearly enough sleep last night.
The thing is that if you wake up in a place that's not your home, you have no immediate idea where you are or how long you've been there. You just hope you're not at a highway rest stop, too far from home and not far enough from the shallow graves you dug. Or maybe that's just me.
Still, I was able to do some writing when I came too. Actually it flowed pretty easily. Score one for disorientation.
