For those who tl;dr'd, basically:
1. Lie in bed and close your eyes. Wait without falling asleep. DO NOT MOVE AT ALL.
2. After a while (10-20 mins) you will get a VERY powerful urge to move. DO NOT MOVE AT ALL
3. there is no 3Turns out this is a way to trick your body that your mind is asleep, so that it goes into sleep mode
while your mind is still awake. Supposedly good for entering lucid dreaming, but it can also lead to night hag syndrome.
The site linked to is a little silly, but the bit above is kosher. I tried it last night. I didn't lie on my back, I settled in my usual position on my side and stayed very still, breathing as if I was asleep. It took less than five minutes for my body to see if I was asleep, and then I felt that weird pressure and total awareness of my body as it started to sleep without me.
Unfortunately it was too intense, I remembered all the nightmares I get and started to freak out about how bad they'd be if I was awake and thought they were real, and for some reason I was sure I'd see something evil with fangs coming out of the closet (which has no door). I brought myself out of it before I'd gone too deep.
Next time I shall try when it's fairly light outside.
