Now as far as I'm concerned, as a skeptical person, I have little reason to believe in shared dreaming.

It's odd, however, that in the descriptions of an "Astral Projector," who traveled to the moon, makes note of structures and people similar to the ways in which you describe them. Whether AP and LD are the same, different in some way, or both occupy the same realm, I think this is what makes me have to try it for myself.

I remember reading about it from her Projection diary, which definitely made me double-take when I first saw this thread.
