Laying down to sleep around 4AM, a bit restless from caffeine that got me through a paper but ready to relax and unwind. Outward vision completely darkened by an eye-mask. Flat on my back, straight spine, no pillows.
Meditation visuals began to sync with my breathing. Ripples of white light, almond-shaped, radiating out from a central point. As soon as one ripple had left, another would burst out from the center. This is a normal meditation experience for me.
But suddenly, a large nebulous blue-indigo shape appeared. I was surprised. I could concentrate on it to make it larger, more vivid. The black background in which it hovered began to shift around, like static.
I attempted to change its color to red by willpower, just to see if I could. I couldn't. The blue disappeared momentarily, as if irritated by my struggling, but came back when I relaxed. I attempted again to change it to green, but this also failed. Eventually I drifted off to sleep.
Any thoughts on this? Please share if so.
