Grats on your first lucid.

You know I was the same for my first. Mine wasn't as vivid as it sounds like yours was but I remember wondering why I didn't attempt to do more. I think with me it was because I was a little shocked. I remember trying to float, failing, then trying to summon a friend of mine and half succeeding. Why didn't I turn my hands into pick axes and start killing zombies? Why didn't I breathe fire and turn the world upside down just to mess with everyone? It all comes with time. I'm assuming when you're more used to the situation you're able to remember to attempt more amazing feats. For instance I successfully flew in my second LD.

As for the dream chain. Yeah. There are people out there who can have chains of lucid dreams even. Look up the DEILD
method.

Again, congrats. Keep it up.
