I recently came into the ability to WILD on command by accident, and this afternoon I kept careful watch on what I experienced as I was slowly sinking through various levels of consciousness, and wrote a blog of it.
"I tried again today to experience WILD, and as I was slipping through various levels of consciousness I kept note of the different experiences, for they were quite interesting.
If you ever want to try this, take a period, say an hour where you have nothing better to do and you feel moderately fatigued, not tired enough to fall asleep. Lie down in bed and assume a comfortable position, but not *too* comfortable. The way I lie down, I sleep on my stomach with my hands under the pillow, and I seem to cross my ankles for this as well.
Then just breathe deep and even, but always always maintain a conscious feel for your body and always watch the inky blackness behind your eyelids. Your not trying to sleep, your trying to control your descent down the levels of consciousness.
Eventually, your heart rate, ironically won’t slow down, it will speed it, it will seem to pound within your chest. You’ll be able to grasp images beginning to appear in that inky black like a pool of liquid spreading outward. Then suddenly as you try to grab firm hold of the image, concentrate on it, it will disappear, and you might feel an odd feeling in your head, or hear a strange boom, and a shiver or tremble might pass through your body.
My theory on this is your brain knows your still awake, so it’s trying not to enter sleep-paralysis while you are awake.
This image appearing and disappearing may happen three or four or more times, but stay vigilant, relaxed, and above all don’t move a muscle, even moving your eyes while you relax can disrupt the process. Your extremities might begin to lose sensation, feel like there is an immense weight upon them, feel like they are floating on water or a cushion of air, and they might feel like they are burning up, have a fever. These I am assuming are all syptoms of sleep paralysis.
Sometimes you skip the ‘flying sensation’ and suddenly the image that appears is actually your brain entering the dream and it spreads outwards until it encompasses your vision, slowly coming into clarity, and you try to move your arms, and you can feel your arms moving, see them moving in your vision yet also, feel them still and unmoving on your body. Since your sleeping so lightly and conscious of the fact, even small noises can cause the image to fall away, so try to maintain a silent atmosphere.
But if you feel the flying sensation, you might hear some strange booms and your body may be covered in shivers that sweep head to toe and back a few times, and then suddenly it'll feel like your spining, like in a gyro machine, or on a roller coaster, this past time it felt like I flew hundreds of feet in the air only to fall back down again, and as I was falling down I could see my arm in the air because of the rate I was falling, and upon reflection, I never moved a muscle, my eyes 'opening' to look at my arm was just my dream beginning.
I you are successfully in WILD, and you wake up, don’t worry, don’t move, and continue the same thing you did to get there, and you’ll re-enter the dream before a minute or two has gone by, unless what woke you is really distracting and constant. On a side note, doing over exciting things in your dream can what I assume to cause a shot of adrenline from your brain and will also wake you up.
And if you’ve gotten to this point, congratulations. Practice it, and when you can repeat it, you should be able to do it at will.
I mean, I had little time due to interruptions today, but I tried my ideas, I flew on the back of two dragons, one was covered in feathers, completely white and had a bird like visage and the other was the run of the mill dragon.
And then I tried my other idea, saw a puddle, jumped into it, and swam in an entire underground world with the ability to breathe underwater, though that worried me, so I left. I was a bit regretful I didn’t see any puddle-people. Got this idea from a website 
, and I need s’more ideas for tomorrow or whenever I feel that sweet-spot of fatigue.
I hope it works for you!"
If any of this is redundant due to imformation you most likely know already I’m sorry 
But WILD came to me out of nowhere, it seems to work best for me only if I’m taking a nap somwhere between 10 am - 2 pm.
Wish you the best of luck in your pursuit of WILD
) is indeed microsleep, and the only thing I can think of right now is keep trying. I’m not sure if actually sleeping for a few hours and having vivid dreams would help the wake-initatied part of the experience any easier.
