This may not help you in attaining lucidity but to make your dreams more vivid and make them easier to remember i suggest starting a vitamin regiment. I am currently taking 200mg of 5-HTP, 250mg of choline bitartrate, 100mg of B6, and also if you have some trouble falling asleep you can take melatonin. I do not suggest taking more than 2mg though because it does slightly supress REM. I also recommend you take these with a meal in the evening before you go to bed.
