Rhythmic Napping

After watching the Salt Cube video (the one about lucid dreaming, I posted a clip about it earlier), I learned about rhythmic napping. Rhythmic napping deals with waking up in the morning after about 5 or 6 hours of sleep, staying awake and then going back to bed. However, while going back to bed I start a timer which is set to go off after 8, 4, 8, 12, 16, 20, 20, and 6 minutes. Each time the timer is supposed to wake you up, but you aren't supposed to move any part. The timer is supposed to help you hover on the awake/sleep threshold (where your mind is awake and your body isn't). The timer can be found here: http://www.lucidology.com/timer/
