Hi Elliot.
I made my own lucid dreaming triggering device. i simply recorded my voice on a cd and i kept repeating things like "you are dreaming, you are alseep in your bed right now and you are dreaming". the whole CD is an hour long and i wake up every morning ay 3:00am and start the cd and then go back to bed. i've had tremendous success with it. none of the other methods help me (WILD, WBTB).
