This is the correct answer. Hakeem was such a maestro - he had moves but what made him unstoppable was his gift was to be able to feel where people were leaning and turn those moves into set ups for an even deadlier set of counter moves that turned a reliable hook shot into an easy up and under lay in or a wide open jumper.
As others have suggested, I think the DS was actually a set of moves or counters — but they pretty much all focused on a drop step, fake one way, go the other — that’s why Yaos base line shake and fadeaway was called the Shanghai Shake. I wouldn’t ever consider the Bamboozling of Robinson to be a “Dream Shake” though. I guess there are two ways to look at it: Dream Shake the move; or Dream Shake, general description of Dream shaking his opponents.
