Not sure if this is the correct place for this thread but i am making this to speculate on the future of dreaming.
I think it will not be too long before we will have tech which would let anyone achieve near 100% ld rates. Having such tech would likely increase public interest in dreaming.

More people lding would mean more people attempting to make not just sd but also mass sd happen.

With many minds and constantly improving tech, i think it likely that a sort of shared dream net could possibly be created and maintained somehow.

People being able to interact within a shared dream net could lead to some pretty huge leaps forward in what human minds are capable of. Specially if time dilation tech is refined to where anyone who wants could achieve mental methusilazation within the shared dream net, the possibilities of what multiple minds working together for vast periods of time could achieve could become mind-boggling with near-limitless implications on both the shared dream net and waking reality.

Do you guys think that a massive shared dream net, functioning sort of like the dream version of the internet, could ever possibly exist? Why or why not? And if so, then how? And how do you think such things could be used to better humanity?
