I had an idea. I wanted to know if it would work.
I theorize that if you have machines that can electrically stimulate the brain and control what you are dreaming, you can have a machine take those little shocks or electricity and put it into another person to then have the receiver receive the same dream and if lucid, have the two people in the same dream, both aware and with both minds connected so each is talking to the other in the dream.
The device would stimulate the brain to create a lucid dream. Then, the other part would then copy over the electric signals and put them into the mind of the second person who would be dreaming the same dream, they then can move around and be lucid and have that signal sent to the first person who would see the second doing the same thing. They even can talk to each other and interact.
It may be vague, but would it work?
If it would work, would it be able to be built?
