Lynn,
For the second one, I think the sentence could go either way, depending on inflection and context. I instinctively read it as A (which is what you intended, right?), but if you emphasized the "hadn't" and put it in context, it could be B. (What an awful dream. She stumbled out of bed to find the mud from the dream decorating the kitchen floor. She wondered if perhaps she hadn't dreamt the whole thing.) Note: Just noticed. The 'altogether' seems to clarify that she thinks it was a dream.
For the first one, I think the sentence is awkward -- in that it takes a couple read-throughs to figure out what exactly you meant (no instinct kicks in like with number two). And after looking at it, I think it clearly says B. Ha had little doubt = He was pretty sure. That = what he's sure of. They weren't the same shoes he'd already bought = They were not the shoes he's already bought.
Any help?
