I never even have tried to WILD while initially going to sleep, but I can do it a lot after sleeping a few hours and semi-waking up. I do also allow my brain to chat to itself and wander as it wants to... but the WILDs usually click in the most when I ask it to visualize whatever it wants to. I don't tend to get those sort of Epic movie-like dreams that sometimes come in the DILDs though.

Another mention is that while I always ask the brain to visualize whatever it wants to, I can sort of guide the visuals with my wishes once they have started. When I first started doing this, I would sometimes see some ugly and scary things, but I learned to mentally walk to them and hug them and tell them they had my unconditional love. They would (every time) instantly turn into a sensation of Love in my Heart. Those were really great sensations.
