I have written on the philosophy board about my experience at the Memphis Zoo where I had the perception that existence is simultaneously one, nothing, infinitely complex, serene at the fundamental level, and extremely beautiful. It was the perception that the Eastern philosphers call "Nirvana," "unity consciousness," or "the seventh state of consciousness." I have never fully explained what was happening in that situation. I had just learned transcendental meditation, I was in a short period where I had virtually no worries at all just after going through the worst period of my life, and I had done LSD for the first time not too long before then. Whatever it was, it was defintately my perception. My last lucid dream involved my sitting in a room at a cabin in the woods, a cabin that does not exist. I looked around the room and knew that it didn't exist, and that thought led me to percieving that nothing exists. It was as though I could clearly see that nothing exists and that all reality is an illusion just like the dream I was having. It might be the coolest lucid dream moment I have had yet. Then I woke up and had the perception that things actually do exist.
