For all of you on the forum that can induce LDs at will every night, can you please tell me the exact mental process that takes place before and as you're going to sleep?

I've had a bunch of LDs, but they seem to happen haphazardly even though I try techniques. Out of 3 - 4 days that I try a MILD or something, It'll only work out of 1 of the days. I can't differentiate what I do differently between the days where I DO have LDs and where I don't.
