Who would think it would be cool if while Ventus was sleeping, there were Dreameaters?

I hope I never see another dream eater again tbh.

I do not understand what is being asked here.

I don't think it's necessary to link it.   If he was I would have hoped that we would have had some vague guidance by a glowing light orb/not body (so we wouldn't know who it is) in DDD like it leading us down a right path in a world where we get no instructions on where to go and it'd be revealed in KH3 to be Ven, but we didn't.  

It might be possible since,

 

when sora is in a enternal slumber riku dive into sora's dream/sleep in order to wake him up when he reached to sora's station of awekening a dark armor appeared (Armored ventus nightmare) and then the nightmare dreameater logo appeared meanwhile riku's shirt have the spirits dreameater logo thing.So um yeah ,Nya~
