Thread: A new world within lucid dreaming (involving shared dreaming)

Well no, the hard part would be shared dreaming.
Personally, I believe that dreams take place entirely in our own brains (as does the conscious thought of our waking life, in my opinion).
So, this would only work if shared dreaming exists, which you seem to be taking as a given.

Let's assume this is all possible.
Everyone needs nutrition to survive - you'd effectively be going into a coma, and with no food or water (you can't eat dream food to live), anyone who tried this would die in a matter of days.

Sorry, not happening.
