Freud describes a similar technique for lucid dreaming in his Interpretation of Dreams.

- Drink a lot of water before retiring to bed.
- Fall asleep
- When you dream about water flowing, or drinking, etc., use it as a dream sign to know that you are dreaming.

This is becaue the feeling of the need to urinate has somatic manifestations in dream content.

The problem with this technique; potential to wet the bed.

Enjoy!
