Yeah, that's kind of what I'm talking about! It's a very specific visualization where it comes and goes and feeds into itself. It's really cool. The brightness you're talking about is legit. It's fun to play with bringing that in and out. A thing that seems to kinda trigger the visualizations I've experienced is to focus on where those blueish blobs disappear into nothing. For me, that looks like an intense brightness kinda sorta collapsing into the center of my vision which happens again starting from the edges of my vision. In a way it feels like I'm watching some low level neuron activity. But if I close my eyes and try to force some sort of visualization, it doesn't happen until I slow down and just pay attention to that middle point between my brain and my vision. Not really a meditator, but I've experienced it the strongest when I'm about to fall asleep. Once I'm in that headspace, I can keep it going until I see those wild, megalithic visualizations.
