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?

What about two or more people entering Astral Projection at around the same time?

yes it would work on the same premise as the lucid dreaming version only using a technique for astral projection. Anymore though I think its hard to separate the astral world from the dream world. The only difference to me is that dreams are a microcosmic representation of our lives and environments and the astral plains are a macrocosm, possibly shared amung all people.

Can they communicate that way?

Communication is also possible just as in dreams. Regardless if you're in dreams or AP the determining factor is the skill of those involved. THe more adept one is at AP or LCDs the more successful the result will be.

Also, could the group "create" an environment while APing and simulate a dream environment?

Skys the limmit bro. The only limmitation is the experience of the practioners. Realize that just by being able to have LCDs or to AP doesn't mean you'll be able to do much else except achieve the altered states of mind. Really mastering a technique for either is like becoming a baby all over again. It takes months even years of riggorous practice to really be good at talking, reading, walking, flying - basically interacting with and manipulating one's environment. Sometimes I've found myself talking in my dream and realized that I was also talking out loud. Or I would be lucid in a dream and walking and wake myself up because I was trying to walk with my actual legs.
