Ok, last weekend i made an experiment with WinXP Scheduled Tasks. First i recorded my voice into a wav file. I said 'You are Dreaming.' Then i arranged a scheduled task which plays the wav file every hour.

Saturday night I went to bed and fell asleep. I slept for 10 hours and the wav file played nine times. I only heard the sound saying 'You are Dreaming' 5 times. 4 out of 5 times the sound made me to wake up. Once i became lucid but i couldnt maintain lucidity.

Sunday night i realized that the sound was too loud so i turned down the volume. I went to bed and fell asleep. I slept for 7 hours. And the wav file played 6 times. Two times i heard the sound 'You are Dreaming' and i became lucid. But i could not maintain lucidity due to lack of experience.

Conclusion:
The Scheduled Tasks program on WinXP is useful on attaining Lucidity. All you have to do is record your own voice saying 'You are dreaming.' And add a scheduled task that plays the sound every hour.
