Sometimes in lucid dreams, I expect other people to be lucid

This is kind of weird. Sometimes when I'm lucid, I am talking to somebody. I say something along the lines of "Holy crap, you're not even real" And they say "What are you talking about?" Then I'm like "Wait! Do a reality check! You're dreaming too!" So basically I believe that if they become concsious of themselves dreaming, we will both be dreaming in the same dream.
A few times though I have said to myself "Wait a minute. You can't be dreaming. This is all in my mind", but not always.

So am I not fully lucid dreaming? Am I not lucid enough to realize 100% of everything that's going on. I certainly feel really lucid. Maybe I'm like 95% lucid.

I don't know if I'm explaining it right, so tell me if you get it or not.

yea if you dont realize ever one is just an extension of yourself and that they are not real then you are either really dumb or not fully lucid

What would happen if you could convince a DC that they were apart of my dream. Would they have controll? or would they just....sublimate or something.

well since they are made up from your sub-conscious, I would assume that they would do what ever you expected them to do.Like if you thought they would fly if they knew they were dreaming, then they would probably fly...
