First thing to remember about shared dreaming is that it does not occur in a shared dream space, each dreamer is in their own unique dream. There are plenty of shared dream accounts online from both parties, and the fact that each dreamer experiences their own unique version of the dream is evident in all of them.
It’s like asking two different people to draw the same thing. There is always differences. These differences are of a personal nature. For instance, in a shared dream account I read involving a father and son, they went to a restaurant. For the father, they went to a Denny’s but in the son’s version, they went to a Wendy’s. Everything else in the dream pretty much the same. These differences that arise are archetypal in nature, different, yet essentially the same thing.
As how to find someone, that’s tricky. For me it’s the same as how I can target someone from their avatar, username, belongings, someone they’ve met. The associations are all there, you just have to send your attention down the right ones. There’s no specific methods that work for everyone, although portals seem to be popular and reasonably effective.
Another option would be to have people meet up at a specific location. I’ve seen this tried several times over the years, meet up at the giza pyramids, the Lucid Cross roads, and many others. All of them were abysmal failures except one, where we met on the moon.
One of the deciding factors of the moon project may have been WakingNomad, who is a living legend when it comes to shared dreaming. I think the real reason the moon worked as a meeting place is because it was so barren. Dreams follow your focused attention, and there is nothing else on the moon to distract that attention from the other people there. That barren landscape draws all the dreamers together, because other dreamers are the only thing there to focus on.
If you’re looking for a group meeting spot, I highly suggest the moon. Lucidity can be elusive, so with a location like the moon, you can use dream incubation to get there.
BTW, flying directly to the moon is doomed to fail. In space you have no reference points, and you can only have movement in relation to something else. It messes up your height/speed ratio.
You don’t really need permission, but my dreams are open to anyone who wants to come pay me a visit. I’m also open to anyone who wants to throw down. Come at me bro!
If anyone wants to fight, since we can beat on each other all night long, I propose a win condition. First one to wake the other one up wins. Or at least when I get sick of looking at you, that’s what’s going to happen, lol. HINT: The death archetype is notoriously unstable and ill defined, so killing someone is akin to having their computer call a subroutine that isn’t there, returning an error and crashing the dream. Disorienting them will also destabilize your opponent’s dream.
I won’t do any lasting harm. Just be warned, I’m really fucking good when it comes to dream combat. I won’t wake you up right away, I’ll toy with you first. Frankly, I think I would own EA, and he’s welcome to prove me wrong any time.
