So, I tried having a WILD last night. I started at about 11:30 PM. I just lay down in a comfortable position and started breathing slowly like I would when sleeping. I lay like this for a while, and after quite a long time my legs began to go numb. I felt like a lead blanket was being pulled over me, just like people described it. I was numb all the way up my legs up to a little before my crotch. After a while my hands started to go numb, but they seemed to just stay in that phase of right before they go numb. After a long time my left hand went completely numb. My right hand didn't go numb. Also I kept lying there until I felt like my chin was going numb but it didn't go any further. Then I finally gave up also because I was hot since my whole blanket was spread on me, but also because I waited for ages lol. I looked at the clock when I got up and it was like 1:30 AM lol I waited for like 2 hours.
Also, sometimes when breathed in or out my legs or arms would sort of twitch.
So what am I doing wrong?

Sorry for the very long post lol.
