My guess is that you’re trying to move your legs in your sleep (see above).
For a moment I thought y’all were talking about dreams about smoking. I haven’t had a cigarette since 1995, but after I quit, I would have dreams in which I’d started smoking again – more often at first, and rarely now. I even feel guilty about it in the dream. I’ve heard these dreams are common among ex-smokers.
I’ve had those dreams. Other recurrent scenarios are that some portion of the house is falling apart, and/or I’ve stumbled into another bedroom that we don’t use for anything/anyone, except storage and completely forgot about the room and whatever’s in it. Also, driving around a city (usually Austin) where the geography/topography is nearly impossibly (but not completely) different from the facts-on-the-ground. Or an airplane crashes nearby while I stand there unable to do anything about it.
I figure, before long, this visitor’s going to return, in my dreams…
