I have used various techniques over the years. For a while, I struggled with WILD but got MILD to work pretty consistently. I would just do the mantra, "I realize it's a dream." over and over while I'm falling asleep after a short WBTB. Later, I learned SSILD as a form of WILD and it worked really well compared to other WILD techniques I tried. This tutorial on SSILD looks pretty good. I haven't tried it in a while and usually rely on DILDs since I'm a bit out of practice.
