The book covers spontaneous and intentional mutual dreaming, and includes lucid and non-lucid examples. An appendix in the back of the book lists references and examples that can be found in other books. There is no bulletin board or mailing list that specializes in mutual dreams, only. You might post your dreams at the alt.dreams and alt.dreams.lucid newsgroups and ask for a response. The two mailing lists that are currently open to discussion and activity are listed below.
People join, start talking about the subject and then suggest a dream-together project.
The participants on this list share dreams, have weekly dream incubation projects, mutual dreaming projects and occasional psi and telepathy dream projects. You may get an email requesting verification. Group dreaming projects often have a facilitator who chooses a goal and then requests people to deliberately incubate dreams about the goal. A meshing goal is an invitation to dream together about a topic or theme.
