The technique i have developed for lucid dreaming is that i would look at my hand very often in the day.When i would look at it i would be fully aware of myself and be fully conscious.At night,while in the dream,if i see my hand even by mistake i would become fully aware.
Another technique i use is that i make a specific hand sign. When I make this hand sign i try to be fully conscious and aware. In the same way, I would make that hand sign in my dream unconsciously but after i have made it, I would become fully conscious.
