I'm glad to know you can to know that you see Xehanort summoning that Dream Eater, but what if Xehanort and Xehanort can summon Dream Eaters too? Maybe Xehanort was the one who sent the Gargoyle Dream Eater in La Cite des Cloches after Riku while Xehanort summoned the Fire Crab Dream Eater after Riku inside Monstro. Maybe Xehanort, Xehanort, and Xehanort are able to harness a Nightmare's power due to them being bad and trying to help them prevent the worlds from waking up while Sora and Riku are good and try to team up with Spirits to help bring back the worlds. But I wonder what would happen if Xehanort has already been revived as Xehanort in the Realm of Light? Perhaps Xehanort might seek out the seeds he sown into Braig and Isa and Xehanort will somehow have them try to team up with Xehanort in KHIII. Then, we might have to face Xehanort, Braig, and Isa in KHIII and after getting Terra out of Xehanort and he reverts back to Xehanort, then we can kick Xehanort's ass!I actually can't see anyone summoning that dream eater.
And at 0:18, can anyone else hear Yen Sid say "Dunna what i do". It's the Japanese language though, but it just sounds like that to me.
Edit: NEVERMIND I SEE THEM!!!
