After I got up, I went down the hall and got my email, back down the hall to retrieve my kindle, back down the hall to my laptop. Never noticed anything.
Still later, came back down the hall to the bathroom, and there was Domokun, standing upright in the middle of the hallway.
We have a string of domo lights around the ceiling in the bathroom, but how he managed to fall off the string and bounce all the way to the middle of the hall, landing in a standing position, I can't imagine. Nor can I say how I managed to walk past him 3 or 4 times and never notice him.
I picked him up and stood him in the incense pot, where he continues to startle me every time I turn on the bathroom light.
