If you want a quick easy way of obtaining lucidity, follow these rules:

Become able to dream recall easily (look for some tutorials on here)

and,

Wear a DAYTIME nicotine patch to bed.

This stimulates the brain in a wierd way when you sleep. Usually when i do this i have about 2 or 3 dreams and in all i am lucid. I remember during the dream that i was also in a differant dream and lucid just a second ago.

BUT BE WARNED! This usually causes nightmares. I don't understand why, but it can do. I'd say there is about a 40% of having a vivid nightmare.

(Note: Do not wear a nicotine patch if you do not smoke, as there is a small chance of you getting addicted plus i don't really want to get sued )

Enjoy
