Most people, myself included use some form of “anchor”. This is something you keep very loose attention on as you fall asleep. Some use a mantra, others visualisation. I find attention on the breath works best for me but still my success rate is low. If you’re falling asleep too fast then try wake yourself up a bit. Use the toilet or write in your journal. It is a tricky thing to achieve but what I’ve found is even if I attempt WILD and fail I still raise my chances of having a DILD when I fall back asleep so it’s all worthwhile.
