I’ve just added a Dreamachine to my web app (epilepsy warning, flashing lights)
The Dreamachine was developed by Brion Gysin (1916-1986) to enter a hypnagogic waking dream state. It uses flashes of light as visual stimulation between 8Hz and 13Hz to change your brainwaves.
The original Dreamachine was inspired by Gysin hallucinating to the sun flickering behind the trees as he traveled past. It was made up of a cylinder with slits that would rotate around a light bulb to create a flicker.
This is similar to the technique used by both Nostradamus and Jan Purkinje ( the father of contemporary neuroscience) to receive hallucinatory visions, by closing the eyes and moving their fingers before the eyelids to interrupt the light source and create a flicker.
Have fun! You can lay back and place your phone over your eyelids, or use a VR headset if you have one (about $5)
We must storm the citadels of enlightenment, the means are at hand.-William S. Burroughs to Brion Gysin
