Yes, but it is different from the chaos present in AoS. In AoS, Soma defeats the flow of chaos that runs through the castle, basically the very soul of the castle, what makes it a creature of chaos. He defeated the Chaotic flow within Dracula's castle.
But since Soma IS Dracula, if his hatred and anger is strong enough, he attracts chaos to himself. Chaotic souls and powers.
To be honest, it would have made so much more sense if Dawn didnt exist...
