Screen, I'm super pumped to see your excitement, but when I brought up "sharing dreams" I meant the physical act of telling someone your dream, not the particular phenomenon of co-dreaming that you speak of. Don't worry, it's no big deal.

And Tygar, you bring up some valid distinctions between lucid and normal dreams. Lucid dreaming in particular has a long way to go as far as even being socially recognized.
Perhaps if there was a hub where people could create genuine quality works of self-expression with the purpose of sharing them with the world, more people would (at the very least) be curious about exploring dreaming a little deeper. I'm just tossing around ideas at this point, but for those of us fortunate enough to have awesome dream experiences, we understand all the ways dreaming (lucid and non-lucid) can positively affect our lives.
