It seems like everyone I've ever heard talk about WILDs have them after having slept for 5-6 hours; is it possible to have them at will without having been sleeping before hand? Like, using some sort of relaxation technique to get your body really relaxed, and just going from there? I've tried to get this to work a couple times and no real luck...so i was just wondering, and what kind of success you all have had with it?
