For the past few years I have meditated 1/2 hour every day, usually at 10pm. My method is to darken the room and "look" at the blackness behind my closed eyelids. It's never truly black as there are phosphenes that are constantly coming, going and changing shapes. But I use these to try and quiet my monkey mind. I can't claim to be very good at it, even after several years, as I get maybe 10 minutes of true quiet mind for every 30 of sitting meditation. I also wear earbuds and listen to a low volume Monroe Institute Hemi-Sync recording.
A few weeks ago, I was towards the end of my meditation when something began to "form" in the phosphene field. It faded in slowly over about 5 seconds and formed the number 1 in the reddish sort of "light" you see when you have your eyes closed. Then it faded out slowly over a few seconds. It was very distinct and brighter than the normal shifting strings and blobs. I noted it at the time, but didn't think too much about it. A couple of days later I was at a gas station and thought I would buy a few lottery tickets. I remembered the number from my meditation. I picked 1 on three tickets and then second guessed myself and didn't pick it on two others. That night, 1 was one of the winning numbers. I thought, that's odd, but probably just a coincidence.
A couple of nights ago, I was again meditating and had the same experience. The phosphenes slowly formed a number that was more distinct and brighter than the normal background noise; 13. Then it faded. This time I played it on four tickets. 13 was one of the winning numbers. I did even manage to win $3.

So, what am I to make of this? More coincidence? It feels a little spooky.
