Dreamachine -- To Create Space-Out
Introduction
Space-out is a feeling that people can never tell exactly what is by themselves which can be seen as the soul leaving the body. The views that people see in front of them when their minds escape from their bodies, are diverse and different from the others and difficult to tell clearly. However, the trigger points of space-out are quite similar, drugs, alcohol even some specific visuals, for example. Dreamachine, as one of the most critical patent of triggering space-out, also known as a piece of art work, is a good example to explore the phenomenon of space-out. In this essay, I will give my research on how dreamachine make efforts on people and why people get the feeling of space-out.
Flicker
“Flicker” is a long-standing term of art in experimental psychology, referring to visual effects induced by flickering lights. In 1945, Dr. W. Grey Walter applied flicker into his EEG research, in the end an electronic stroboscope was invented. After an experiment in a big range of people, Dr Walt got the feedbacks (strange feelings) from samples he chose, which were:" faintness or swimming in the head"; "unresponsive or unconscious for a few moments"; "the limbs jerked in rhythm with the flashes of light."
As shown in the diagram on the right, eyes receive the lights from the strobes (lamp) as an subjective experienced signal which is transmitted to our brain, then, the signal (brainwave) goes through the recorder make efforts on the trigger.This loop can be seen as the basic prototype of how the visual flicker we look at works on our brain.
" We all noticed a peculiar effect . . . a vivid illusion of moving patterns whenever one closed one’s eyes and allowed the flicker to shine through the eyelids. The illusion . . . takes a variety of forms. Usually it is a sort of pulsating check or mosaic, often in bright colours. At certain frequencies—around 10 per second—some subjects see whirling spirals, whirlpools, explosions, Catherine wheels. " Dr Walter noted after experimented with strobes on himself.
However, those illusions are similar to the hallucinogenic effects of psychoactive drugs such as LSD and mescaline, which is one of the most important reason why it becomes popular in 1960s and led to the invention of dreamachine.
Dreamachine
In the post-World War II era, the Beat Generation rediscovered the drug-like strobe machine by reading Dr Walt's book The Living Brain. It starts with an experience of Brion Gysin, a painter, writer, sound poet, and performance artist born in Taplow, Buckinghamshire. In his dairy he wrote: " Had a transcendental storm of colour visions today in the bus going to Marseilles. We ran through a long avenue of trees and I closed my eyes against the setting sun. An overwhelming flood of intensely bright colors exploded behind my eyelids: a multidimensional kaleidoscope whirling out through space. I was swept out of time. I was out in a world of infinite number. The vision stopped abruptly as we left the trees. Was that a vision? What happened to me? " After reading Dr Walt's book The Living Brain which is lent by William S. Burroughs, Gysin found the answer and built the Dreamachine in the early 1960's by putting a cylinder with holes onto a record player turntable, a light bulb was put in the middle of the cylinder, when the record player being set to spin at 78 round per minute, the strobes turns into the visual of sitting in a bus and passing shades of leaves under the sun.
The light flickers at a frequency of about 20 Hz which is similar to the frequency of Alpha brain waves which are associated with a non-aroused brain.
Brion Gysin found the explanation for this unusual experience a few years later when S. Burroughs lent him a copy of The Living Brain by Dr. W. Grey Walter. Dr. Walter was a neurophysiologist and an early researcher into the nature of brain waves and corresponding brain function. Ian Sommerville, a friend of Gysin and Burroughs, had also read the book. Sommerville decided to build a machine to reproduce the flickering effect that Gysin had described. On February 15, 1959 Sommerville wrote to Gysin from Cambridge, "I have made a simple flicker machine. You look at it with your eyes shut and the flicker plays over your eyelids. Visions start with a kaleidoscope of colors on a plane in front of the eyes and gradually become more complex and beautiful, breaking like surf on a shore until whole patterns of color are pounding to get in. After awhile the visions were permanently behind my eyelids and I was in the middle of the whole scene with limitless patterns being generated around me. There was an almost unbearable feeling of spatial movement for a while but It was well worth getting through for I found that when it stopped I was high above the earth in a universal blaze of glory. Afterwards I found that my perception of the world around me had increased very notably. All conceptions of being dragged or tired had dropped away..."
From Sommerville's description of the flicker machine Brion Gysin in the Beat Hotel on the rue Gît-le-Cœur, Paris. Gysin obtained a patent in 1961. The results of the experiments were published in the arts periodical of Olympia, Number 2, January 1962.
