Lucid dream. I was teaching class and all was going horribly wrong so I walked very far  across a campus to my office where I poured red wine into a silver togo cup. When I left to return all the buildings had changed. "Lara," I said, "This is not possible. This is nothing like reality. You are dreaming. You do not have to get back to class. Nothing will happen. Just go. Go!" It took a little convincing since the responsibility to fulfill my obligation to my students was very powerful. Finally, I capitulated to my rational mind. I bounded away like a freed animal across soft hills. I met strangers with whom I engaged kinky sex and/or interviewed them as usual: "Who are you, exactly?" They revealed nothing.
