Step 5What to expect and other brain hacks
Effects of Ganzfeld are not immediate. It can take time to get anything but everyone is bound to experience something special. With practice this improves.
When someone wears a Ganzfeld mask, the progression of effects that can be described as follows:
All color drains from the field of vision
The size of the field of vision oscillates
Swirling kaleidoscope of colors appear
Images suddenly pop in the visual field
In a recent neuroscience article, a researcher described his first experience with Ganzfeld as follows:
For quite a long time, there was nothing except a green-greyish fog. It was really boring, I thought, ah, what a non-sense experiment! Then, for an indefinite period of time, I was off, like completely absent-minded. Then, all of sudden, I saw a hand holding a piece of chalk and writing on a black-board something like a mathematical formula. The vision was very clear, but it stayed only for few seconds and disappeared again. The image did not fill up the entire visual field, it was just like a window into that foggy stuff. ...
...an urban scenery, like an empty avenue after a rain, large areas covered with water, and the city sky-line reflected in the water surface like in a mirror...
....suddenly, a young woman passed by on a bicycle, very fast, she crossed the visual field from the right to the left, with her blond long hair waving in the air. The image of the entire scene was very clear, with many details, and yes, the colours were very vivid. ...
....A friend of mine and I, we were inside a cave. We made a fire. There was a creek flowing under our feet, and we were on a stone. She had fallen into the creek, and she had to wait to have her things dried. Then she said to me: Hey, move on, we should go now. ...

I never try anything like this until I know what will happen...
