Three nights ago, that seemed to stabilize. I went to bed at a reasonable time, and slept the night through for the first time in probably ten days. That's not the weird part: the weird part is that when I woke up, somebody had taken my wok and made stir-fry.
The doors were all locked. Sadie didn't bark at anybody.
I put the stir-fry in some tupperware and popped it in the freezer.
The last two nights have been the same: I sleep the night through and wake up in the morning to chinese-style food; this morning it was Kung Pao pork. The doors are all locked, nothing else is disturbed.
I think I may be sleepwokking.
