This is exactly how I go into LD.

I meditate (tanscendal meditation) and I repeat Buddhist Mantras, and eventually I get to a state of blackness, and being one with the blackness.
Here I repeat the mantra i devised to induce LD "I will fall asleep and will lucid dream" this is reapeated as many times as possible till i fall asleep.

when i started doing LD Last year I used the mantra "I will wake up and remeber my dream after every dream" to start of and after about two weeks replace it with the Ld mantra. I really works if you are devoted to it, it realieves stress aswell.

NO weed required

Much love OM MANI PADME HUM
