I read about one of the methods mentioned here, that one must lie still, and not move the body at all for twenty minutes or so. This will trick the body into drifting into sleep, while the mind is still awake. I tried this method, but I became extremely bored after 30 mins or so, I quit.

I did experience the following, though. I felt as if my feet had disappeared (meaning there was no solid feeling), and my palms felt a tingling sensation. There were some minor sensations throughout the body, but these two experiences were more pronounced.

Can the experts tell me where I am going wrong, and how I can make adjustments so this technique can work?
