I had my 2nd lucid dream this morning, shortly before waking up. I knew almost from the start that I was dreaming, as I examined the environment (an office space where I last worked), and then started interacting with the people there, after I realized that they saw me and thought I belonged there with them. At one point I started telling a female co-worker (that I thought I knew as a friend), that I wasn't really there, that I was dreaming.
Everything in the dream looked real, and very detailed, but as I moved around and through the environment, I realized that it kept changing layout, an impossibility in the real world. That's how I first confirmed that I was dreaming. As I continued to explore the place it got more elaborate and colorful. It started out as a single-level mostly white office place, but eventually looked more and more like a shopping mall with escalators and balconies and lots of shapes and colors. And the costumes of the people went from normal to neo-Victorian, with bowa and ruffles on men's jackets, and made of brightly colored and shiny fabrics, almost looking clownish.
When we all found ourselves outside on a country road, a departed from the group, walking toward a wooded area away from town. Then I awoke, and remembered everything I had just dreamt.
