Are DC’s all different? Like say I was in a massive crowd of people, would they all look different? ex. faces, legs, hair, etc
Yes, yes they would. Your mind can make any mixture of faces, hair voices and all. It can even copy people you just see in passing in your day to day life to add to the effect.
Wow. This is truly amazing. Thanks for the help. 
Yes of course they can all be different. Basically anything can happen in a dream. They can all have pink elephants as pets and have crocodiles sticking out of their heads 
BTW, how did you not figure this out by personal experience? Have you never dreamed before?
Actually, they could all look the same. It depends on how your mind creates them. Or maybe most are different and others are not. The most interesting thing I’ve noticed about them though is that a single DC can change many forms through the dream. I always know who they are, but when I wake up I realise that they never had a specific image.
Short answer: They can be different, but not necessarily. Dreams are crazy and random.
Ah yes, we forgot to mention that. I always hate those dreams when I’m looking for someone but end up trapped in a crowd of people who all look the same.
