I've been using something like this method for a while. When I close my eyes, it doesn't take long for blots of color to swirl around in my vision. Their primary color is bluish-purple for me. Indigo. This hypnotizes me into dreaming sleep. I don't think it's for a rods-and-cones type reason, though. For me, it's about distracting my mind enough to fall asleep while still maintaining a fragile hold on awareness. |
