Somewhere I read recently some ways to increase the frequency of lucid dreams... One of them was to simply think about lucid dreaming before going to sleep and so I tried it and I think I had a small degree of success. It'd actually been quite a while since my last lucid dream, which was why I was interested to read that article. One of these short bursts of lucid dreaming started as a regular dream that was beginning to go bad - I'd gotten myself onto a steep roof and was gradually sliding off it. I wanted to roll over a bit so I could fetch up against some wall or something right at the edge of the roof but I couldn't manage that (prolly some mild sleep paralysis...). As this all got a bit more intense, right at the edge of the roof, I decided to leap instead of just dropping off, which is a neat trick for the paralysed, but I didn't fall, I flew. It'd also been a while since I'd had a flying dream. As this was happening I knew it was a lucid dream and the whole thing was holding together instead of dissolving into wakefulness and I was so pleased with myself I was flying around trying to prove to myself that it was a proper lucid dream by following trivial conscious trains of thought like doing simple arithmetic... Somehow, even when I haven't gotten to a properly lucid state, when whatever it may be is about to get me, I face it and go on the attack - typically the reward for that is the nasty dream sequence ends and a new, non-threatening dream begins.
