These TaR dreams can be metaphorical, and they can be obscure... But willingly accepting a person's help to proceed together? That's not an attack that managed to work to Egwene's advantage. Certainly not one that cost her dearly and would make her dead-set against them.
I'd say it's quite obvious it'll be be something else. I'll try to give you a possible scenario:
Maybe Rand will know her anger, but he'll have found a terangreal that makes people realize how asinine and self-righteous they can be. This would simply devastate a character like Egwene.
In one of the many moments of weakness that result from her humiliation, Egwene will accept help from a Seanchan army in fighting off a super-horde of Trollocs and Myrdraal, 400,000 in total.
Mat later makes a bet with Tuon - if Rand kneels once to her, she'll give up the Empire's slavery with the exception of Nynaeve. The Lightside gladly give up the oldest Wonder Girl. Now that they're "tame," Egwene ends up working with the Seanchan for the rest of the Last Battle. She will have many monologues wherein she thinks about how much she hates them, while simultaneously thinking about how many things they do well. Egwene will eventually start claiming that she's learned/mastered some aspect of them that she considers admirable.
Rand fakes his death after the LB, and she thinks she's safe from his accursed terangreal. Then she decides to use some of the weaves she learned at Tarmon Gaidon. One of them allows her to berate and harass people over a 2-league area. She uses this ability to get most of the Seanchan to return to their old territory.
