Parallel Dream/Universe

I was thinking about this for a little bit, it sounds crazy and probably isn't correct, but it's a neat idea.
Scientists talk about how there are parallel universes out there, and that there is a type of universe that is in the same exact location another.
People also talk about shared dreaming here on this forum.
What if when we believe to be awake, we are dream sharing, we cannot do whatever we want because of everyone else stopping us from doing it unconsciously.
When we Lucid dream, we are breaking out of the shared dream and actually go to our own universe where we are free to do what ever we want. The reason is it so hard to start Lucid Dreaming is because you are trying to break away from the shared dream and everyone elses presence.
I don't know, it seemed like a strange idea.

Hmm... Interesting, except that would mean if we had dreams with friends in it, then they would have to be asleep too. I know, that people can dream about people who are awake at the time...
