I had my first LD last night. I've only been trying for about a week. I had a few vivid dreams and then I realized that I was dreaming. I don't know what made me realize it though. I was really exited but then I realized that if I didn't calm down, I would wake up. I forgot that I was dreaming and went on. Later I remembered that I was dreaming, and remained lucid for what felt like 15 minutes. I've heard that LD's are very realistic, but I was completely amazed at how real the dream felt. I really had to ask myself if I was dreaming. I noticed that there was no reason to be were I was (a random building that sort of looked like my gym class). I tried a couple of things like jumping, pinching my self (witch did hurt, I thought it wasn't supposed to hurt?), and I tried changing somethings (nothing happened and I didn't try too hard so that I wouldn't wake up). It was such an amazing experience, if felt kind of like everything just came into focus. I really can't believe that the mind can create such a realistic world.
