“A visual flicker is known to induce “Ganzfeld imagery” (Allefeld et al., 2011; Sumich et al., 2018), a type of visual pseudo-hallucination. The continuous flicker facilitates visual imagery, but does not induce any permanent changes in the brain and does not elicit actual hallucinations. I am interested to learn about the association between any illusions you see, and the vividness of your visual imagery.”
–Ganzflicker Experience
Go to a dark room, put on the white noise, and bring up the image and do F11 to make it full screen. Watch for 10 minutes. I found the experience a bit, uncomfortable, sensory overload and my eyes do not like bright flashes of light. But, I both saw things and had auditory hallucinations. So, weird enough to mention on this blog. Read a fuller article on pseudo-hallucinations, if you are so inclined.
