Download this timer:

Then go to bed at 9PM or 10PM ish, wake up around 4:00AM and STAY AWAKE for about 45 minutes. Go back to bed, start playing the timer (on an ipod, laptop, computer) and relax and try to fall asleep. The timer will wake you up at different times in it's 2 hour span. When it wakes you up, try NOT TO MOVE, or it will mess up your sleep paralysis. Let the timer do everything for you, and let it keep waking you up.

After a while, you'll anticipate the timer beeps, and will hopefully go lucid in a dream when you hear this outside noise.

I've tried this once, and had a pretty successful night.
