this has been coming more prevalent to me lately...
I get these alot!
fireflies if I look up at a blue sky, looking at my floaters a lot.
I don't ever press on my eyes really but...
in low-light conditions there is video 'noise' which as i've been paying more attention to it, relaxing into it... it becomes more defined, not geometry but, more colors/points/information.
often when I go to sleep I will slowly dim the lights over a 10 minute period... the video noise becomes more and more. I leave the lights on their lowest point and offhandedly stare at patterened cloth or mandalas. relaxing everything and focussing on not focussing on any one point in the visual field.
something very curious has been happening regularly. my eyes are open, but the light levels begin to fluctuate... in a very steady cycle. no matter what I am looking at, my vision will eventally start fading completely to black... in a cycle that repeats every.. 4-7 seconds.. first one eye, then the other.. it's definitely circular.
at any time during this I can feel my eyes are open.. it's not like eyes drooping closed... I gaze for quite a while and when my eyes start to hurt from being open so long, I can blink.. move my gaze a little. and everything looks totally normal. but I can relax back into it seconds later and the cycling effect is there.
I wear glasses usually and pay a lot of attention to my peripheral vision. the brain is very good at filling in the gaps... it feels like what is happening here is relaxing and letting your brain fill in the gaps.
I have read about how in the dreamstate, your creative workspace is feeding the visual field... and when awake it's the immediate physical workspace that feeds the visual field. and at some point between asleep and awake, this workspace swap happens...
I feel like this field swap is something in this state... it feels different from sensory deprivation.. more like sensory surrendering. my thoughts while watching like this are often.. not caring about what is right infront of me. looking at my hands and letting them seem completely alien...
another thing that is prominent when doing this activity is.. there is a tone.. it's not tinnitus, I have that rarely and know what it sounds like... this is much higher pitched. reminds me very much of the tryptamine tone.. it's like I can feel my brain working. and the more I relax into it and let my visual field be taken over by blackness and phosphenes.. the more strength the tone has.
possible manifestation of brain waves resonating with cells in the retina/inner ear/sensory parts of the brain? or just what happens when you start to really pay attention to your input and state of mind??
I couldn't even begin to say at this point...
