The first thing that hit me with that dream was that Ichigo had his old Shikai and its appearance again, I was wondering if Kubo screwed up and totally forgot Ichigo's current appearance.

Yhwach is weird though, dreaming of his own apparent death and then grinning when he wakes up. I guess it was more a kind of "heh, like he would actually manage to hurt me in real life!".

As for Jugo, if you haven't read it before, his power is thought to be The Balance, being able to balance fortune and misfortune to his advantage. If it'll turn out to be that, I guess it's as simple as he could use it to make Uryu unlucky with his attacks and give himself more luck.
