It's tough when they're so sleepy! One of mine was super sleepy (ds, I think?) and I can remember stripping him down to a diaper and feeding the first side that way, then changing his diaper midway through to wake him up again and then getting him dressed and swaddled for the second side -- at least then I thought he was getting a decent feed.
For the dream feed, you might try shifting it 15 minutes in either direction (earlier or later) if you haven't already to try to catch her in a lighter stage of sleep. And give burping a try after the DF as well - I know that Tracy says in the books that babies don't need to be burped after the dream feed, but mine definitely did need to be burped.
You can always try resettling too with a paci or some patting (none of mine ever took the paci so that never worked for us) -- but if she keeps waking over and over it's almost definitely due to hunger and you should feed her. Feeding is your best course of action if it's been more than a few hours, but you're right, the waking an hour after the last feed sounds more like discomfort from not burping. DH was always a champion burper for my LOs, he used to rub their backs opposite their little tummies while they were sitting up and it worked better than the patting I was doing.
