Could this "shrinking" world be a result of a migraine headache, or other
constriction of blood-flow to the brain?

I got two migraines (I'm told so; my head didn't hurt) about 18 mo ago. 
The first effect I saw was the world shrinking, much as decribed in this
string, then I got tunnel vision, then finally, I got a "sparkly"
blob shaped patch with a dark middle in the center of my right eye
field of view. All the fun quit after half an hour of lying down. It
hasn't come back since I cut down to 3 cups of coffee a day ("Caffeine,
just say No!").

I've also had a shrinking effect, though more commonly a "distancing" 
effect--in which I seem to retreat to the other side of a screen from 
the world--when I've had the 'flu and related fever.
