That's another odd thing. There is no real "setting." I only seem to focus on the foot actually cramping and the pain. It's only the feeling/pain and I'm never "anywhere else." I have no idea what else is around me or going on. The pain seems to last 'forever,' of course, but I quickly get 'out' of the dream once it's over, and never really wake up right afterward.
It would make sense--I agree with you--that maybe this is about how the illness affects and limits my life. As I'm sure you would agree, it's not easy living with all this 'stuff'!
