At night when Im laying there I run all kinds of crazy things through my head. I thought Id run a idea buy you guys and see what you think. I suppose this could be possible.

What if when you dream your consciousness leaves your body and travels to a parallel universe. So this dream world your in is a real place, you just cant seen it when your awake but can see it while asleep when your consciousness is no longer in your body.

So when you see people in your dreams they could be real people who are also dreaming.

Lets say you are dreaming of shopping at walmart, all those people you see are also dreaming of being at walmart.

So the dream I had where I tried to beat up that math teacher may of had some math teacher dreaming he was teaching class and some idiot tried to beat him up.

This is just a theory of mine, I think its possible that something along these line could be true.
