A while ago I had this strange experience as I was attempting WILD. When I went to bed, I relaxed my body and I started to count. I tried to make sure that my mind didn’t wander and if it did, I quickly brought it back to concentration. While I was doing this, I felt this odd sensation where it felt like someone was putting a blanket over my body, and my eyes started to twitch, and eventually my body had this strange vibration. I assume this might have been a part of the process of wild, but all of a sudden, it just stopped. I opened my eyes to check if I was dreaming, I wasn’t. Then I was tired and I didn’t really feel like trying again, so I went to sleep. Why did it all just stop?
The vibrating sensation and twitching is your body relaxing and begining to numb. Basically the start of a WILD . I dont know why it would stop though other than loss of focus. Just keep trying, you’ll get it soon. 
same with me but dont stop! stopping wastes time
Yeah, that happens to me a lot too. The vibrations just go away. 
I haven’t even gotten to the vibrations in a while… I miss them. 
I guess we just have to keep trying!
The vibrations are a hallucination. You don’t actually move at all. I you can remain calm and concentrated while the vibrating happens, you can be quite close to success.
