Dreamspeak, communicating with others through dreams Options

Can one send messages or have conversations with others in a shared dream? For example, let's say I want to speak to someone in another city and the person to whom I wish speak is already asleep. I then induce a lucid dream/astral projection and visit that person in a shared dream. Whether I induce a dream in them, "pull" them into my dream, or "connect" both of our dreams together is irrelevent to me. I want to be able to have a conversation with someone via dreaming, the same way video chat is done over the internet. Is this possible and if so how do I go about doing it?

=P
My sleep is never really deep and my dreams aren't very lucid. I can't stop dreaming about sex though so good luck, I probably wouldn't be able to tell it apart from an ordinary dream...=P
Aren't sexual dreams associated with power or something? Like if you dream of being raped...you want to be dominated, and if you dream of controlling of someone, you want the upper-hand/more power. I have absolutely no idea if that's right, I heard it somewhere..

Anyway I know this isn't related and I'm not desperate to have this skill (although it sounds fun enough)-there was a girl on Big Brother who could orgasm with just her thoughts, how do you do that?

Is it something that takes a lot of self-control and visualisation? Or can some people do it and some people can't?
Or can everyone do it? Or am I the only one who can't do it?


Am I allowed to ask that question...
