Wow, that's a pretty impressive lucid dream for being new at it. Heck it was pretty impressive even for us more experienced LDers! So yeah, I think you should start a dream journal and try to have some more man.

As far as the shared dreaming thing you mentioned, I personally don't buy it. But there is a section on this forum where it's discussed along with other related stuff like that, if you're interested: Beyond Dreaming.

Anyway, welcome to DV, I'm sure you'll find all sorts of interesting stuff here to suit all your dreaming tastes.
