First, congratulations on that lucid.It must've been amazing. It's really wonderful what the subconscious mind is capable of doing, isn't it?
I was thinking of visiting mind blowing landscapes recently, and after your experience, I might just yell out for an amazing scene and see what my subconscious has to offer me.
Second, I've noticed that your WorkBook is well-orgnaized and every thing is in order, and that certainly helps when you try to go back and check your progress. I like my things to be in perfect order but I fail at that miserably, and you can check my Workbook to be sure of what I'am talking about.
Keep on dreaming!
