From some faq:
2.12. What is PILD (Punishment Induced Lucid Dream)?
This technique works by punishing yourself every time you fail to realize that you were
dreaming. While going to sleep, tell yourself that you MUST become Lucid this night OR you will
be punished in the morning. Various types of punishment may be a cold shower or maybe an
electric shock. A 9 volt battery against your tongue maybe. This technique should be used in
combination with MILD. The point is to increase your intention, and it works.


Has anyone tried this, or even 'Reward ILD' seems kinda extreme to me, but maybe worth a shot if you are having trouble.
