They seemed to be able to note how to get out of the way of any magic their owners happened to be casting, at the very least. Not that Aqua had had any doubts about the intelligence of the Dream Eaters, mind. All the same, it couldn't be denied that for all her Pricklemane was doing its very best impression of a spiky wrecking ball (and doing quite well at dealing with it's chosen opponent, at that.)

For her part, Aqua simply made another swooping gesture with her Keyblade, freezing a nearby cluster of Nightmares before the ice imprisoning them simply shattered. Conveniently enough the ice shards that resulted didn't seem much inclined to deal any significant damage; although the unfortunate Nightmares were once again sent flying.
