Ok. To try and get the ball rolling.

Because Lucidty is not always a sure thing for anybody then you add another person to the mix. This makes it more difficult.
So I suspect time will be an issue in this experiement. But time we have.

We need someone to act as the third party.
Who would like to do this?

We don't know what factors are important for shared dreaming.
The possibilities include what? Just brain storming here. Add to the mix if anyone thinks of another factor.

I don't think we have twins in the forum?
boyfriend/girlfriend
husband/wife
friends over the forum
Same interests
same sleeping patterns*
Date of birth
boy/boy
girl/girl
girl/boy

Having said all that. If we can find two participants and a third party to relay the dreams.
We need to discuss wether techniques are important.
More brain stroming.
Do both individuals follow the same methods for becoming lucid?
Opon becoming lucid;
both have a predetermined set of proceedueres
a place to meet?
