> 5. Start removing thoughts from your brain. As you start thinking about something, just stop. Another thought comes in. Kill it. Just kill thoughts. You can think only about your breathing. Nothing else. If only it was this easy!! It almost feels like a variation of "start outlining the owl... now when you have the outline, just draw the rest of the owl". :-)
Here's a technique that works for me: So, when I close my eyes I can "see" things. I don't know if it's light coming trough my lids or blood vessels or just my mind's eye. I don't know. But what I'll do as a last resource when I have trouble sleeping is to pay full attention to those things and find patterns in them. I even say out loud in my mind like: "oh there's a dog", "a canoe", "a cigarrette". Then I'm dreaming…
Years later I realized that I could make them appear at-will by wiggling my eyes around (a la REM), and that lead me to conclude that it's likely my overly-long (i'm severely myopic) eyeballs physically stimulating my optic nerves.
I don't notice it as much lately, and I avoid doing it on purpose, in case it's not healthy.
