This is an idea I’ve had for a while now. I forget whether I ever posted about it, but the idea has morphed quite a bit since then regardless.
The basic idea is this: Multiple people keep dream journals, and attempt to build a shared “canon” between their dreams. This is done through lucid dreaming and/or dream incubation.
The process would go like this: Person A posts a dream journal entry detailing a particularly interesting dream. Person B, after reading the dream, attempts to dream about one or more aspects to the original dream and explore them further, taking all or most of the original journal entry as “canon”. Aspects that can be explored might be locations or characters, or even more abstract stuff, like fictional organizations or larger plots. Person C (or person A or B again) then takes both these journals as canon, and attempts to have a new dream building off of those. The next person then builds off of these, etc.
This could, potentially, be a really interesting world-building exercise, or better, could have participants be part of an ongoing story in the dreamworld. Participants might not actually meet one-another in their dreams, but they could witness the effects of one-another’s past presence.
In the case of contradictory experiences, participants can discuss these IWL to resolve contradictions.
The process could also be supplemented by artwork, music, or other such things made by different participants.
This could work as both an open thread (in which anybody can join or leave at any time) or in more limited-sized groups with signups.
Wonder if anyone would be interested in trying this.
