It was totally AMAZING! It's the longest I've ever been lucid. And yes, as a writer, it was quite an experience. It's been on my dream bucket list for a while I feel like I was lucid (or at least aware) for most of the dream. Though once or twice, I felt my vision getting weaker, and I thought I might be slipping out of lucidity. Not sure though, still new at this. It was a fantastic dream nonetheless.
Sounds like a fun experience and adventure Seeing the characters from your own book must've been pretty amazing. How long did the lucid last?
