For some time, I've been attempting a WILD a couple of times a week. Every time, things happen roughly the same way (tl;dr: I always fall asleep very quickly, unless I attempt a WILD, in which case I can't get to sleep for a good 30-60 minutes after I've aborted the attempt).
Before bed, I drink a glass of water. When I go to bed, I fall asleep very quickly - usually in less than 5 minutes. At some time during the night, I wake up. I record my dreams in my journal, assuming I can remember them. If I haven't slept for at least 5 hours, I drink more water and go back to bed (again, falling asleep in less than 5 minutes); otherwise I continue. Lying in bed (sometimes on my side, sometimes on my back), I relax myself completely, usually with self hypnosis. I tell myself that my body is going to fall asleep while my mind stays alert.
At this point I've tried various things. Sometimes I lift the trance but stay relaxed; sometimes I stay in the trance. Either way, I try to keep my mind clear. I've tried focusing on my breathing; focusing on a the flame of an imaginary candle; focusing on the sound of the room's fan. Often I get bright flashes, and sometimes I try to focus on them. Sometimes I'll try a mantra; other times I'll count down from 100, including (or not) a brief mantra between numbers, sometimes counting with my breathing, sometimes not. Sometimes I'll try to visualize the dream I want to be in; sometimes I'll try to generate random, unconnected imagery. I almost never have trouble staying still: I can hold a position on my side or back for upwards of half an hour without discomfort.
It seems that no matter what I do, I end up waking myself up more and more. I'll usually still feel drowsy when I go back to bed (I'm only up for 5-10 minutes, and I don't turn any lights on). I know the first thing you have to do with a WILD is to fall asleep, and I haven't been able to find a way to fall asleep with any semblance of awareness. Any thought I try to hold in my mind seems to make sleep abandon me completely. Any drowsiness I had going back to bed quickly disappears.
Worse yet, when I abort one of these attempts (usually after 40 minutes to an hour), I've usually "forgotten" how to sleep altogether! Sometimes I'm able to get back to sleep after another 30-60 minutes of trying to get to sleep; other times I end up getting up for an hour and going back to bed when I feel tired again.
These nights aren't a complete waste: the few DILDs I've had have almost always been on failed WILD nights.
I know that falling asleep is a very personal thing, and that no one can give me a precise recipe. Even so, is there something obvious that I've overlooked?
