Woah, I experienced this a lot when I was younger. I never knew it had a name. Before I went to sleep I would see all kinds of crazy patterns and colours, sort of like blurry fractals I guess. Level 3 describes it well, but I wouldn't say I spent a long time concentrating and I definitely hadn't taken any psychedelics at that young age. After a period of time a small spinning... twitch... would appear at the very centre of my vision, the best way to describe it would be a spasm of small lines. Anyone else experienced this? I never really thought it was odd until now, to be honest it kind of scared me. I assumed it was sort of tinnitus for your eyes, and I was somehow damaging them!
