Hi and welcome to Dream Views Skibbaz.

I've heard that shared dreaming is possible but I've yet to experience it. I'm no expert on electrical signals and magnetic fields but I'm thinking that the signals in the mind might be too minimal to affect the mind of someone nearby. If that could happen I think there would be greater instances of shared dreaming documentation. That's my 2 cents and it's probably wrong.

Again welcome and don't rub my face in my wrongnss.:p
