Lucid Dreaming and Virtual Reality

For the past few days I've been thinking, what if in the future (hopefully soon), scientist come up with a technology which basically connects people's dreams. So, like "mutual" or "shared" dreams, as some people call them. And let's say that it's an advanced technology which sends you straight into a lucid dream by synchronizing your brain's waves. And how to connect the dreams? well this technology would read each person's brainwaves and interpret (very accurately) what the person is doing on the dream and instantly send it to the other person's dream, so basically what's happening in one person's dream would also be happening in the other person's dream. Of course, people wouldn't have 100% control of their lucid dream, for example they wouldn't be able to change the environment, or make the other person explode.
Also, I am talking about virtual reality games, so let's say that you go to this "Lucid Dreaming Virtual Reality Centre" there you can choose a game, for example Dragon Ball Z or something, you go to the DBZ aisle, which would contain many rooms, and in each room there are 30 "Lucid dream induced virtual reality,errrr.. beds?" so 30 people can join the same dream and have their cool dragon ball z fights, or explore a world together, fight against villains together.

Do you guys get my idea? Do you think this would be possible? and do you think they can come up with this, let's say, in the next 40 years?
