SCILD is a method I have tested and had positive results. SCILD = "Sky Check Induced Lucid Dreaming"

Instructions - You must form a habit of everytime you go outside, leave the house or get out of your car you must look at the ground for a second and picture the sky being the color purple in your mind. Look downwards with the sky completely out of your veiw and make yourself beleive the sky is purple then look up to see if it is. If not you are awake if so you are dreaming. Make sure you do this everytime you go outside! <IMPORTANT!

Outcome - After doing this for about two days you flawlessly will have a ld every night!
