I created this method as an off shoot of the MILD technique. What I did was use the mantra,“The next time I open my eyes, I’ll be dreaming.” Then I close my eyes and try to keep them closed. Assuming you do actually have a dream and you don’t break your mantra and open your eyes, you’ll most likely succeed in LDing.
P.S. If you do open your eyes, just repeat the mantra again and try to stick to it.
Let me know if my method worked for you.
