This frequency range corresponds to alpha waves, electrical oscillations normally present in the human brain while relaxing.
It’s high time: The Dreamachine is no longer just a dream
The Dreamachine is "viewed" with the eyes closed: the pulsating light stimulates the optical nerve and alters the brain's electrical oscillations. The "viewer" experiences increasingly bright, complex patterns of color behind their closed eyelids. The patterns become shapes and symbols, swirling around, until the "viewer" feels surrounded by colors. It is claimed that viewing a Dreamachine allows one to enter a hypnagogic state. Initially, most users observe something akin to a perpetually metamorphosing Persian rug. Within 10 to 15 minutes, entoptic effects are likely to segue into a series of cinematic images, as the brain endeavors to find order in an otherwise endless, abstract chaos.
During this process, sensitive users may enter lucid dreaming. Normally, an awake person's brain functions at between 4 and 8 electrical pulses per second hertz, or hz.

When the Dreamachine's 10 flickers per second strike closed lids, however, the optic nerve sends a 10 hz pulse signal into the cortical tissue. Because the amplitude of the newly introduced signal is greater than that of the waking brain's normal frequency, the waking brain now operates at 10 hz, the synaptic rate associated with the edge of dreams.
The reason for its five discrete shapes lies in the mathematically calculated rate of flicker generated by precise placement of a lamp fixture within the rotating cylinder.
The user sits or stands very close to the machine nose approximately two inches from cylinder , eyes closed. The flickering light induces Alpha waves to defeat Beta waves normally active in the "awake" brain. By subtly shifting facial positioning and proximity to the machine, an Alpha range of light interruptions hz opens to the user.
Effects of such periodic waves on the human brain vary among users. Delta waves HZ. Delta is associated with deep sleep.
In creating their own version of this iconic Dreamachine device — which they named the Castillo de la Esfera — the pair faced a number of challenges, not least to make sure that the final piece would both sit flat in the jacket and also fold into a perfect cylinder. Being conscious of the budget constraints, the duo pushed for the freedom to see this dream realised.
