Is Shared Dreaming an alternate universe or realm?

I was just thinking the other day, that wouldn't shared dreaming have to be an alternate universe or realm or whatever you want to call it.
I personally think shared dreaming is real, although I have no personal experience with it, but wheather it is or not doesn't really matter. If you don't believe it than "pretend" that it is real for a second. From what we know, dreams goes on in our brains, but if two people could share a dream what would that make it? Would it be a shared mind or what?
Anyway, just leave your oppinion or comments on the subject.

Shared dreaming does not occur in a stable realm. It actually happens a lot like RL. Take two people, one who is an animal lover and another who got mauled by a dog as a child, and have them booth look at the same pitbull. They will not see the same thing. The animal lover will see an adorable animal, and the mauling victim will see monster. Each participant in a shared dream experiences their on personal version of that "reality", the only thing that is shared are common archetypes.

I have been doing a number of personal experiments in my lucid dream travels and it is my opinion that there might be a collective unconscious that our consciousness taps into when we go to sleep. I believe that it is a realm of pure creativity and what you personally believe and want to believe will come true. What appears is as individual as the person themselves and in shared dreaming I believe that two people's consciousness' cross on occasion, hence causing a shared dream. Just a theory

Well Shared Dreaming could be like a alternate universe or realm. It is like a universe you create with your own imagination. But i am not sure of this because i have never had a shared dream with anyone......yet.

Imagination and belief are irrelevant. Dreams form around your personal preexisting archetypal structures. Beliefs are nothing but archetypal structures of their own, and your imagination is limited by those same structures. I wouldn't have awesome Doctor Who time travel dreams if I didn't watch doctor who to begin with. Watching that show repeatedly builds up archetypal structures, which then manifest in my dreams.

We can share dreams in different places. All these places are made of pure energy. We will see the energy in different ways based on our archetypes. It is more than a meeting of minds.
