I've just joined this site last week, but I've been reading about lucidity for years. I haven't managed it, until last night! In the first dream I suddenly became lucid for no apparent reason, and I noticed the dream was fading. I tried rubbing my hands together to stabilize it, and I tried saying 'Dream Clarity!' or something like that, but they didn't work. Eventually I just blinked a couple times and walked forwards a few steps, and SNAP! Clear as anything! I didn't manage to exercise my control in that dream, but in the second one I was being chased by crocodiles, and as I was swimming away I thought, hang on, this isnt real, I dont need to be scared! I made the crocs dissappear just by thinking 'crocs go away'. for some reason I created a bathtub for me to float in. I woke up at that point.
It was great. Hopefully I can advance to flying and so on.
